Getting Started

+

+ A designer knows he has achieved perfection not when there is nothing + left to add, but when there is nothing left to take away. - Antoine de + Saint-Exupéry +

+
+ +Fat-Free Framework makes it easy to build entire Web sites in a jiffy. +With the same power and brevity as modern Javascript toolkits and libraries, +F3 helps you write better-looking and more reliable PHP programs. One glance +at your PHP source code and anyone will find it easy to understand, how +much you can accomplish in so few lines of code, and how powerful the results +are. + +F3 is one of the best documented frameworks around. Learning it costs +next to nothing. No strict set of difficult-to-navigate directory structures +and obtrusive programming steps. No truck load of configuration options +just to display `Hello, World` in your browser. Fat-Free gives you a lot of freedom +- and style - to get more work done with ease and in less time. + +F3's declarative approach to programming makes it easy for novices and +experts alike to understand PHP code. If you're familiar with the programming +language Ruby, you'll notice the resemblance between Fat-Free and Sinatra +micro-framework because they both employ a simple Domain-Specific Language +for ReSTful Web services. But unlike Sinatra and its PHP incarnations (Fitzgerald, +Limonade, Glue - to name a few), Fat-Free goes beyond just handling routes +and requests. Views can be in any form, such as plain text, HTML, XML or +an e-mail message. The framework comes with a fast and easy-to-use template +engine. F3 also works seamlessly with other template engines, including +Twig, Smarty, and PHP itself. Models communicate with F3's data mappers +and the SQL helper for more complex interactions with various database +engines. Other plug-ins extend the base functionality even more. It's a +total Web development framework - with a lot of muscle! + +## Enough Said - See For Yourself + +Unzip the contents of the distribution package anywhere in your hard drive. +By default, the framework file and optional plug-ins are located in the +`lib/` path. Organize your directory structures any way you want. +You may move the default folders to a path that's not Web-accessible for +better security. Delete the plug-ins that you don't need. You can always +restore them later and F3 will detect their presence automatically. + +**Important:** If your application uses APC, Memcached, WinCache, XCache, or a filesystem cache, + clear all cache entries first before overwriting an older version of the framework with a new one. + +Make sure you're running the right version of PHP. F3 does not support versions earlier than PHP +5.3. You'll be getting syntax errors (false positives) all over the place because new language +constructs and closures/anonymous functions are not supported by outdated PHP versions. To find +out, open your console (`bash` shell on Linux, or `cmd.exe` on Windows):- + +``` +/path/to/php -v +``` + +PHP will let you know which particular version you're running and you should get something that +looks similar to this:- + +``` +PHP 5.3.15 (cli) (built: Jul 20 2012 00:20:38) +Copyright (c) 1997-2012 The PHP Group +Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies +``` + +Upgrade if necessary and come back here if you've made the jump to PHP 5.3 or a later release. +If you need a PHP 5.3+ hosting service provider, try one of these services: + +* [A2 Hosting](http://www.a2hosting.com/2461-15-1-72.html) +* [DreamHost](http://www.dreamhost.com/r.cgi?665472) +* [Hostek](http://hostek.com/aff.php?aff=364&plat=L) +* [SiteGround](http://www.siteground.com/index.htm?referrerid=155694) + +## Hello, World: The Less-Than-A-Minute Fat-Free Recipe + +Time to start writing our first application:- + +``` php +$f3=require('path/to/base.php'); +$f3->route('GET /', + function() { + echo 'Hello, world!'; + } +); +$f3->run(); +``` + +Prepend `base.php` on the first line with the appropriate path. Save the above code fragment as +`index.php` in your Web root folder. We've written our first Web page. + +The first command tells the PHP interpreter that you want the framework's functions and features +available to your application. The `$f3->route()` method informs Fat-Free that a Web page is +available at the relative URL indicated by the slash (`/`). Anyone visiting your site located +at `http://www.example.com/` will see the `'Hello, world!'` message because the URL `/` is +equivalent to the root page. To create a route that branches out from the root page, +like `http://www.example.com/inside/`, you can define another route with a simple `GET /inside` +string. + +The route described above tells the framework to render the page only when it receives a URL +request using the HTTP `GET` method. More complex Web sites containing forms use other HTTP +methods like `POST`, and you can also implement that as part of a `$f3->route()` specification. + +If the framework sees an incoming request for your Web page located at the root URL `/`, +it will automatically route the request to the callback function, +which contains the code necessary to process the request and render the appropriate HTML stuff. +In this example, we just send the string `'Hello, world!'` to the user's Web browser. + +So we've established our first route. But that won't do much, except to let F3 know that there's +a process that will handle it and there's some text to display on the user's Web browser. If +you have a lot more pages on your site, you need to set up different routes for each group. +For now, let's keep it simple. To instruct the framework to start waiting for requests, +we issue the `$f3->run()` command. + +**Can't Get the Example Running?** If you're having trouble getting this simple program to run +on your server, you may have to tweak your Web server settings a bit. Take a look at the sample +Apache configuration in the following section (along with the Nginx and Lighttpd equivalents). diff --git a/content/home/download.md b/content/home/download.md new file mode 100644 index 0000000..373d7ee --- /dev/null +++ b/content/home/download.md @@ -0,0 +1,23 @@ +#### Start Now + +There's no better time to start developing Web applications the easy way than right now! + + + + Download the latest release + + +or grab the [nightly build](https://github.com/bcosca/fatfree/archive/dev.zip).

The framework +will serve any request URL that matches the `/brew/` prefix, like `/brew/99`, `/brew/98`, +etc. This will display `'99 bottles of beer on the wall'` and +`'98 bottles of beer on the wall'`, respectively. Fat-Free will also accept a page request for +`/brew/unbreakable`. (Expect this to display `'unbreakable bottles of beer on the wall'`.) When +such a dynamic route is specified, Fat-Free automagically populates the global `PARAMS` array +variable with the value of the captured strings in the URL. The `$f3->get()` call inside the +callback function retrieves the value of a framework variable. You can certainly apply this +method in your code as part of the presentation or business logic. But we'll discuss that in +greater detail later. + +Notice that Fat-Free understands array dot-notation. You can certainly use `@PARAMS['count']` +regular notation, which is prone to typo errors and unbalanced braces. The framework also +permits `@PARAMS.count` which is somehow similar to Javascript. This feature is limited to +arrays in F3 templates. Take note that `@foo.@bar` is a string concatenation, +whereas `@foo.bar` translates to `@foo['bar']`. + +Here's another way to access tokens in a request pattern: + +``` php +$f3->route('GET /brew/@count', + function($f3,$params) { + echo $params['count'].' bottles of beer on the wall.'; + } +); +``` + +You can use the asterisk (`*`) to accept any URL after the `/brew` route - if you don't really +care about the rest of the path: + +``` php +$f3->route('GET /brew/*', + function() { + echo 'Enough beer! We always end up here.'; + } +); +``` + +An important point to consider: You will get Fat-Free (and yourself) confused if you have both +`GET /brew/@count` and `GET /brew/*` together in the same application. Use one or the other. +Another thing: Fat-Free sees `GET /brew` as separate and distinct from the route +`GET /brew/@count`. Each can have different route handlers. + +## Dynamic Web Sites + +Wait a second - in all the previous examples, we never really created any directory in our hard +drive to store these routes. The short answer: we don't have to. All F3 routes are virtual. They +don't mirror our hard disk folder structure. If you have programs or static files (images, CSS, +etc.) that do not use the framework - as long as the paths to these files do not conflict with +any route defined in your application - your Web server software will deliver them to the +user's browser, provided the server is configured properly. + +### PHP 5.4's Built-In Web Server + +PHP's latest stable version has its own built-in Web server. Start it up using the following +configuration: + +``` +php -S localhost:80 -t /var/www/ +``` + +The above command will start routing all requests to the Web root `/var/www`. If an incoming +HTTP request for a file or folder is received, PHP will look for it inside the Web root and send +it over to the browser if found. Otherwise, PHP will load the default `index.php` (containing +your F3-enabled code). + +### Sample Apache Configuration + +If you're using Apache, make sure you activate the URL rewriting module (mod_rewrite) in your +apache.conf (or httpd.conf) file. You should also create a .htaccess file containing the following: + +``` apache +RewriteEngine On +RewriteCond %{REQUEST_FILENAME} !-f +RewriteCond %{REQUEST_FILENAME} !-d +RewriteCond %{REQUEST_FILENAME} !-l +RewriteRule .* index.php [L,QSA] +``` + +The script tells Apache that whenever an HTTP request arrives and if no physical file (`!-f`) or +path (`!-d`) or symbolic link (`!-l`) can be found, it should transfer control to `index.php`, +which contains our main/front controller, and which in turn, invokes the framework. + +The `.htaccess file` containing the Apache directives stated above should always be in the same +folder as `index.php`. + +You also need to set up Apache so it knows the physical location of `index.php` in your hard +drive. A typical configuration is: + +``` apache +DocumentRoot "/var/www/html" + + Options -Indexes FollowSymLinks Includes + AllowOverride All + Order allow,deny + Allow from All + +``` + +If you're developing several applications simultaneously, a virtual host configuration is easier +to manage: + +``` apache +NameVirtualHost * + + ServerName site1.com + DocumentRoot "/var/www/site1" + + Options -Indexes FollowSymLinks Includes + AllowOverride All + Order allow,deny + Allow from All + + + + ServerName site2.com + DocumentRoot "/var/www/site2" + + Options -Indexes FollowSymLinks Includes + AllowOverride All + Order allow,deny + Allow from All + + +``` + +Each `ServerName` (`site1.com` and `site2.com` in our example) must be listed in your +`/etc/hosts` file. On Windows, you should edit `C:/WINDOWS/system32/drivers/etc/hosts`. A reboot +might be necessary to effect the changes. You can then point your Web browser to the address +`http://site1.com` or `http://site2.com`. Virtual hosts make your applications a lot easier to +deploy. + +### Sample Nginx Configuration + +For Nginx servers, here's the recommended configuration (replace ip_address:port with your +environment's FastCGI PHP settings): + +``` nginx +server { + root /var/www/html; + location / { + index index.php index.html index.htm; + try_files $uri /index.php; + } + location ~ \.php$ { + fastcgi_pass ip_address:port; + fastcgi_index index.php; + fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name; + include fastcgi_params; + } +} +``` + +### Sample Lighttpd Configuration + +Lighttpd servers are configured in a similar manner: + +``` +$HTTP["host"] =~ "www\.example\.com$" { + url.rewrite-once = ( "^/(.*?)(\?.+)?$"=>"/index.php/$1?$2" ) + server.error-handler-404 = "/index.php" +} +``` + +## Rerouting + +So let's get back to coding. You can declare a page obsolete and redirect your visitors to +another site: + +``` php +$f3->route('GET|HEAD /obsoletepage', + function($f3) { + $f3->reroute('/newpage'); + } +); +``` + +If someone tries to access the URL `http://www.example.com/obsoletepage` using either HTTP GET +or HEAD request, the framework redirects the user to the URL: `http://www.example.com/newpage` +as shown in the above example. You can also redirect the user to another site, +like `$f3->reroute('http://www.anotherexample.org/');`. + +Rerouting can be particularly useful when you need to do some maintenance work on your site. You +can have a route handler that informs your visitors that your site is offline for a short period. + +HTTP redirects are indispensable but they can also be expensive. As much as possible, +refrain from using `$f3->reroute()` to send a user to another page on the same Web site if you +can direct the flow of your application by invoking the function or method that handles the +target route. However, this approach will not change the URL on the address bar of the user's +Web browser. If this is not the behavior you want and you really need to send a user to another +page, in instances like successful submission of a form or after a user has been authenticated, +Fat-Free sends an `HTTP 303 See Other` header. For all other attempts to reroute to another +page or site, the framework sends an `HTTP 301 Moved Permanently` header. + +## Triggering a 404 + +At runtime, Fat-Free automatically generates an HTTP 404 error whenever it sees that an incoming +HTTP request does not match any of the routes defined in your application. However, +there are instances when you need to trigger it yourself. + +Take for instance a route defined as `GET /dogs/@breed`. Your application logic may involve +searching a database and attempting to retrieve the record corresponding to the value of +`@breed` in the incoming HTTP request. Since Fat-Free will accept any value after the `/dogs/` +prefix because of the presence of the `@breed` token, displaying an `HTTP 404 Not Found` +message programmatically becomes necessary when the program doesn't find any match in our +database. To do that, use the following command: + +``` php +$f3->error(404); +``` + +## Representational State Transfer (ReST) + +Fat-Free's architecture is based on the concept that HTTP URIs represent abstract Web resources +(not limited to HTML) and each resource can move from one application state to another. For this +reason, F3 does not have any restrictions on the way you structure your application. If you +prefer to use the [Model-View-Controller](http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller) +pattern, F3 can help you compartmentalize your application components to stick to this paradigm. +On the other hand, the framework also supports the +[Resource-Method-Representation](http://www.peej.co.uk/articles/rmr-architecture.html) pattern, +and implementing it is more straightforward. + +Here's an example of a ReST interface: + +``` php +class Item { + function get() {} + function post() {} + function put() {} + function delete() {} +} + +$f3=require('lib/base.php'); +$f3->map('/cart/@item','Item'); +$f3->run(); +``` + +Fat-Free's `$f3->map()` method provides a ReST interface by mapping HTTP methods in routes to +the equivalent methods of an object or a PHP class. If your application receives an incoming +HTTP request like `GET /cart/123`, Fat-Free will automatically transfer control to the object's +or class' `get()` method. On the other hand, a `POST /cart/123` request will be routed to the +`Item` class' `post()` method. + +**Note:** Browsers do not implement the HTTP `PUT` and `DELETE` methods in regular HTML forms. +These and other ReST methods (`HEAD`, and `CONNECT`) are accessible only via AJAX calls to the +server. + +If the framework receives an HTTP method that's not implemented by a class, +it generates an `HTTP 405 Method Not Allowed` error. F3 automatically responds with the +appropriate headers to HTTP `OPTIONS` method requests. The framework will not map this request +to a class. + +## The F3 Autoloader + +Fat-Free has a way of loading classes only at the time you need them, +so they don't gobble up more memory than a particular segment of your application needs. And +you don't have to write a long list of `include` or `require` statements just to load PHP +classes saved in different files and different locations. The framework can do this +automatically for you. Just save your files (one class per file) in a folder and tell the +framework to automatically load the appropriate file once you invoke a method in the class: + +``` php +$f3->set('AUTOLOAD','autoload/'); +``` + +You can assign a different location for your autoloaded classes by changing the value of the +`AUTOLOAD` global variable. You can also have multiple autoload paths. If you have your classes +organized and in different folders, you can instruct the framework to autoload the appropriate +class when a static method is called or when an object is instantiated. Modify the `AUTOLOAD` +variable this way: + +``` php +$f3->set('AUTOLOAD','admin/autoload/; user/autoload/; default/'); +``` + +**Important:** Except for the .php extension, the class name and file name must be identical, +for the framework to autoload your class properly. The basename of this file must be identical +to your class invocation, e.g. F3 will look for either `Foo/BarBaz.php` or `foo/barbaz.php` when +it detects a `new Foo\BarBaz` statement in your application. + +## Working with Namespaces + +`AUTOLOAD` allows class hierarchies to reside in similarly-named subfolders, +so if you want the framework to autoload a PHP 5.3 namespaced class that's invoked in the +following manner: + +``` php +$f3->set('AUTOLOAD','autoload/'); +$obj=new Gadgets\iPad; +``` + +You can create a folder hierarchy that follows the same structure. Assuming `/var/www/html/` is +your Web root, then F3 will look for the class in `/var/www/html/autoload/gadgets/ipad.php`. The +file `ipad.php` should have the following minimum code: + +``` php +namespace Gadgets; +class iPad {} +``` + +Remember: All directory names in Fat-Free must end with a slash. You can assign a search path +for the autoloader as follows: + +``` php +$f3->set('AUTOLOAD','main/;aux/'); +``` + +## Routing to a Namespaced Class + +F3, being a namespace-aware framework, allows you to use a method in namespaced class as a route + handler, and there are several ways of doing it. To call a static method: + +``` php +$f3->set('AUTOLOAD','classes/'); +$f3->route('GET|POST /','Main\Home::show'); +``` + +The above code will invoke the static `show()` method of the class `Home` within the `Main` +namespace. The `Home` class must be saved in the folder `classes/main/home.php` for it to be +loaded automatically. + +If you prefer to work with objects: + +``` php +$f3->route('GET|POST /','Main\Home->show'); +``` + +will instantiate the `Home` class at runtime and call the `show()` method thereafter. + +## Event Handlers + +F3 has a couple of routing event listeners that might help you improve the flow and structure of +controller classes. Say you have a route defined as follows: + +``` php +$f3->route('GET /','Main->home'); +``` + +If the application receives an HTTP request matching the above route, F3 instantiates `Main`, +but before executing the `home()` method, the framework looks for a method in this class named +`beforeRoute()`. In case it's found, F3 runs the code contained in the `beforeRoute()` event +handler before transferring control to the `home()` method. Once this is accomplished, +the framework looks for an `afterRoute()` event handler. Like `beforeRoute()`, +the method gets executed if it's defined. + +## Dynamic Route Handlers + +Here's another F3 goodie: + +``` php +$f3->route('GET /products/@action','Products->@action'); +``` + +If your application receives a request for, say, `/products/itemize`, +F3 will extract the `'itemize'` string from the URL and pass it on to the `@action` token in the +route handler. F3 will then look for a class named `Products` and execute the `itemize()` method. + +Dynamic route handlers may have various forms: + +``` php +// static method +$f3->route('GET /public/@genre','Main::@genre'); +// object mode +$f3->route('GET /public/@controller/@action','@controller->@action'); +``` + +F3 triggers an `HTTP 404 Not Found` error at runtime if it cannot transfer control to the class +or method associated with the current route, i.e. an undefined class or method. + +## AJAX and Synchronous Requests + +Routing patterns may contain modifiers that direct the framework to base its routing decision on +the type of HTTP request: + +``` php +$f3->route('GET /example [ajax]','Page->getFragment'); +$f3->route('GET /example [sync]','Page->getFull'); +``` + +The first statement will route the HTTP request to the `Page->getFragment()` callback only if an +`X-Requested-With: XMLHttpRequest` header (AJAX object) is received by the server. If an +ordinary (synchronous) request is detected, F3 will simply drop down to the next matching +pattern, and in this case it executes the `Page->getFull()` callback. + +If no modifiers are defined in a routing pattern, then both AJAX and synchronous request types +are routed to the specified handler. + +Route pattern modifiers are also recognized by `$f3->map()`. \ No newline at end of file

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + +When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + +To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + +For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + +Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + +For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + +Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + +Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + +The precise terms and conditions for copying, distribution and +modification follow. + +TERMS AND CONDITIONS + +0. Definitions. + +"This License" refers to version 3 of the GNU General Public License. + +"Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + +"The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + +To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + +A "covered work" means either the unmodified Program or a work based +on the Program. + +To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + +To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + +An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + +1. Source Code. + +The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + +A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + +The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + +The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + +The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + +The Corresponding Source for a work in source code form is that +same work. + +2. Basic Permissions. + +All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + +You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + +Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + +3. Protecting Users' Legal Rights From Anti-Circumvention Law. + +No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + +When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + +4. Conveying Verbatim Copies. + +You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + +You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + +5. Conveying Modified Source Versions. + +You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + +a) The work must carry prominent notices stating that you modified +it, and giving a relevant date. + +b) The work must carry prominent notices stating that it is +released under this License and any conditions added under section +7. This requirement modifies the requirement in section 4 to +"keep intact all notices". + +c) You must license the entire work, as a whole, under this +License to anyone who comes into possession of a copy. This +License will therefore apply, along with any applicable section 7 +additional terms, to the whole of the work, and all its parts, +regardless of how they are packaged. This License gives no +permission to license the work in any other way, but it does not +invalidate such permission if you have separately received it. + +d) If the work has interactive user interfaces, each must display +Appropriate Legal Notices; however, if the Program has interactive +interfaces that do not display Appropriate Legal Notices, your +work need not make them do so. + +A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + +6. Conveying Non-Source Forms. + +You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + +a) Convey the object code in, or embodied in, a physical product +(including a physical distribution medium), accompanied by the +Corresponding Source fixed on a durable physical medium +customarily used for software interchange. + +b) Convey the object code in, or embodied in, a physical product +(including a physical distribution medium), accompanied by a +written offer, valid for at least three years and valid for as +long as you offer spare parts or customer support for that product +model, to give anyone who possesses the object code either (1) a +copy of the Corresponding Source for all the software in the +product that is covered by this License, on a durable physical +medium customarily used for software interchange, for a price no +more than your reasonable cost of physically performing this +conveying of source, or (2) access to copy the +Corresponding Source from a network server at no charge. + +c) Convey individual copies of the object code with a copy of the +written offer to provide the Corresponding Source. This +alternative is allowed only occasionally and noncommercially, and +only if you received the object code with such an offer, in accord +with subsection 6b. + +d) Convey the object code by offering access from a designated +place (gratis or for a charge), and offer equivalent access to the +Corresponding Source in the same way through the same place at no +further charge. You need not require recipients to copy the +Corresponding Source along with the object code. If the place to +copy the object code is a network server, the Corresponding Source +may be on a different server (operated by you or a third party) +that supports equivalent copying facilities, provided you maintain +clear directions next to the object code saying where to find the +Corresponding Source. Regardless of what server hosts the +Corresponding Source, you remain obligated to ensure that it is +available for as long as needed to satisfy these requirements. + +e) Convey the object code using peer-to-peer transmission, provided +you inform other peers where the object code and Corresponding +Source of the work are being offered to the general public at no +charge under subsection 6d. + +A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + +A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + +"Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + +If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + +The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + +Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + +7. Additional Terms. + +"Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + +When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + +Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + +a) Disclaiming warranty or limiting liability differently from the +terms of sections 15 and 16 of this License; or + +b) Requiring preservation of specified reasonable legal notices or +author attributions in that material or in the Appropriate Legal +Notices displayed by works containing it; or + +c) Prohibiting misrepresentation of the origin of that material, or +requiring that modified versions of such material be marked in +reasonable ways as different from the original version; or + +d) Limiting the use for publicity purposes of names of licensors or +authors of the material; or + +e) Declining to grant rights under trademark law for use of some +trade names, trademarks, or service marks; or + +f) Requiring indemnification of licensors and authors of that +material by anyone who conveys the material (or modified versions of +it) with contractual assumptions of liability to the recipient, for +any liability that these contractual assumptions directly impose on +those licensors and authors. + +All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + +If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + +Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + +8. Termination. + +You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + +However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + +Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + +Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + +9. Acceptance Not Required for Having Copies. + +You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + +10. Automatic Licensing of Downstream Recipients. + +Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + +An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + +You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + +11. Patents. + +A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + +A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + +Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + +In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + +If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + +If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + +A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + +Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + +12. No Surrender of Others' Freedom. + +If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + +13. Use with the GNU Affero General Public License. + +Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + +14. Revised Versions of this License. + +The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + +If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + +Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + +15. Disclaimer of Warranty. + +THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + +16. Limitation of Liability. + +IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + +17. Interpretation of Sections 15 and 16. + +If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + +END OF TERMS AND CONDITIONS diff --git a/lib/log.php b/lib/log.php new file mode 100644 index 0000000..eb938e5 --- /dev/null +++ b/lib/log.php @@ -0,0 +1,60 @@ +write( + $this->file, + date($format). + (isset($_SERVER['REMOTE_ADDR'])? + (' ['.$_SERVER['REMOTE_ADDR'].']'):'').'
