+
+Simple PHP Wrapper for Twitter API v1.1 calls
+
+[](https://packagist.org/packages/j7mbo/twitter-api-php)
+[](https://travis-ci.org/J7mbo/twitter-api-php)
+[](https://packagist.org/packages/j7mbo/twitter-api-php)
+
+**[Changelog](https://github.com/J7mbo/twitter-api-php/wiki/Changelog)** ||
+**[Examples](https://github.com/J7mbo/twitter-api-php/wiki/Twitter-API-PHP-Wiki)** ||
+**[Wiki](https://github.com/J7mbo/twitter-api-php/wiki)**
+
+[Instructions in StackOverflow post here](http://stackoverflow.com/questions/12916539/simplest-php-example-retrieving-user-timeline-with-twitter-api-version-1-1/15314662#15314662) with examples. This post shows you how to get your tokens and more.
+If you found it useful, please upvote / leave a comment! :)
+
+The aim of this class is simple. You need to:
+
+- Include the class in your PHP code
+- [Create a twitter app on the twitter developer site](https://dev.twitter.com/apps/)
+- Enable read/write access for your twitter app
+- Grab your access tokens from the twitter developer site
+- [Choose a twitter API URL to make the request to](https://dev.twitter.com/docs/api/1.1/)
+- Choose either GET / POST (depending on the request)
+- Choose the fields you want to send with the request (example: `array('screen_name' => 'usernameToBlock')`)
+
+You really can't get much simpler than that. The above bullet points are an example of how to use the class for a POST request to block a user, and at the bottom is an example of a GET request.
+
+Installation
+------------
+
+**Normally:** If you *don't* use composer, don't worry - just include TwitterAPIExchange.php in your application.
+
+```php
+require_once('TwitterAPIExchange.php');
+```
+
+**Via Composer:**
+
+```bash
+composer require j7mbo/twitter-api-php
+```
+
+How To Use
+----------
+
+#### Set access tokens ####
+
+```php
+$settings = array(
+ 'oauth_access_token' => "YOUR_OAUTH_ACCESS_TOKEN",
+ 'oauth_access_token_secret' => "YOUR_OAUTH_ACCESS_TOKEN_SECRET",
+ 'consumer_key' => "YOUR_CONSUMER_KEY",
+ 'consumer_secret' => "YOUR_CONSUMER_SECRET"
+);
+```
+
+#### Choose URL and Request Method ####
+
+```php
+$url = 'https://api.twitter.com/1.1/blocks/create.json';
+$requestMethod = 'POST';
+```
+
+#### Choose POST fields (or PUT fields if you're using PUT) ####
+
+```php
+$postfields = array(
+ 'screen_name' => 'usernameToBlock',
+ 'skip_status' => '1'
+);
+```
+
+#### Perform the request! ####
+
+```php
+$twitter = new TwitterAPIExchange($settings);
+echo $twitter->buildOauth($url, $requestMethod)
+ ->setPostfields($postfields)
+ ->performRequest();
+```
+
+GET Request Example
+-------------------
+
+Set the GET field BEFORE calling buildOauth(); and everything else is the same:
+
+```php
+$url = 'https://api.twitter.com/1.1/followers/ids.json';
+$getfield = '?screen_name=J7mbo';
+$requestMethod = 'GET';
+
+$twitter = new TwitterAPIExchange($settings);
+echo $twitter->setGetfield($getfield)
+ ->buildOauth($url, $requestMethod)
+ ->performRequest();
+```
+
+That is it! Really simple, works great with the 1.1 API. Thanks to @lackovic10 and @rivers on SO!

# Git Process
This is the core part of the Git session: how to use the Git?
-### Prerequisite
+### Prerequisites
In order to use Git on your computer, you might need to install an app. After install the required app, every Git process is done either on the Github website or on your command-line app.
- If you're using **Mac**, it is possible that Git is already installed along with Xcode. Try to open "Terminal" app, and type `git` and hit "enter". If not installed, Mac will automatically open a window to install Git.
@@ -153,47 +153,8 @@ Type:
```
git push origin master
```
- By default, your branch is "master". Later, you can create other branches as needed.
-
-### Collaborating with your Colleague(s)
-For your own project, you normally use `commit` and `push` to manage your code, but not other commands that much. However, Git is often for collaboration with other colleagues. Let's do some exercises on collaborating with your friend.
-
-1. Peer up with a colleague on your next. On the browser, go to your friend's Git repo page by typing your friend's Git repo URL. For example, you may go to `https://github.com/UMD-DCIC/INST742-git`
-2. Click the "Folk" button at the top.
-3. Once you folk your friend's repo, you just copied your friend's precious project to your account.
-4. Go to your folked repo page (you can see it in your repo list on your main Git page).
-5. Go to the terminal, get out of your original repo folder. For example:
-
- ```
- cd ..
- ```
-6. Clone your folked repo to your computer. The steps are same to before, but just the address of the repo is different. If not sure, follow the steps in [Cloning a Git Repo](#clone).
-7. Get into the cloned repo folder. Remember, this is a repo "folked" from your friend's account.
-
- ```
- cd [name of the folked repo]
- ```
-8. In the folked folder, there is a file that your friend created. Let's create another file.
- - Open your text editor, create a new file, write something in it, and save it in the folked repo folder with your name (e.g., `[your_name].md`).
- - Add, commit, and push your change.
- - Once pushing your changes, your file is uploaded to your folked Git repo, not your friend's repo. But you want to give your changes to your friend.
-9. Go to the web page of your folked repo. There is a button called "New Pull Request". Click it.
-10. You will see "base fork" and "head fork" in the web page. "Base fork" is the original repo that you want to contribute to (in this case, your friend's repo). "Head fork" is your folked repo that you just made changes. You are basically trying to ask your friend to merge your changes.
-11. If you see the "Create Pull Request" button (in green), click it. Then, you can write down a message about your contribution. Once you make a pull-request, your friend will receive the request from his or her email or on the Github website. **Now, as a contributor, your work is done.**
-12. As an original project owner, you receive a pull request from your friend. In your original project repo page, you can see there is one pull request. Click "Pull requests" menu.
-13. You can see your friend's message. If you have any opinion, you can comment on it as well. This conversation can go on as a thread. Once you're satisfied with your friend's contribution, click the `Merge Pull Request` button. Don't click `Comment and Close` button unless you don't want to merge it. Subsequenlty, it is possible that you need to click `Confirm merge` to complete the merge.
-14. Once it says it was successfully merged, your project is finally contributed by your friend. As a contributor, you also made success in contributing to your friend's project.
-
-### Pulling Your Repo (Github → Your PC, whenever there're any changes on Github)
-Your Git repo has been contributed by your friend, but your computer still doesn't have your friend's contribution, because you accepted your friend's pull request online and never downloaded the new changes onto your computer. In this case, you need to "pull" the up-to-date changes.
+ By default, your branch is "master". Later, you can create other branches as needed.

-2. Type this:

- git pull origin master
- ```
-3. Then, your friend's recent contribution will be downloaded to your computer.

+
+### Exercise: Folking and Contributing to the Original Code Base
+1. Go to this Git repo web page: `https://github.com/myeong/INST377`
+2. Click "Folk"
+3. Go to your folked repo. It should be something like `https://github.com/[your_id]/INST377`
+4. Clone it to your PC.
+5. Go to `git/introductions/` folder, and create a Markdown file with your last name. `[your_last_name].md`
+6. Open the file, write down any one sentence in the Markdown file, and save it.
+7. In the command line, `git add .`
+8. `git commit -m "my name added"`
+9. `git push origin master`
+10. On the Github repo page, click "pull request" button and submit your pull request.
+11. The instructor comments on the pull requests and merges them.
+12. Now, your change has been applied to the original project repository.
+13. Check the registered Git addresses by typing `git remote -v`
+14. You want to pull the most recent changes to your local computer. In order to do that, your PC needs to know the address of the original repo.
+Type `git remote add upstream https://github.com/myeong/INST377.git`
+15. Check again whether the original repo has been registered.
+ - `git remote -v`
+16. The original repo that you are contributing to is now registered on your local folder.
+17. You pull down the most recent changes on your computer by typing
+ - `git fetch upstream`
+18. You merge "upstream" to your local repo.
