+# Payment processing example: PHP
+
+This sample demonstrates processing card payments with Square Connect API, using the
+Square Connect PHP client library.
+
+## Setup
+
+### Install the PHP client library
+
+This sample already includes the `square/connect` dependency in its `composer.json`
+file. To install the client library:
+
+1. Make sure you've downloaded Composer, following the instructions
+[here](https://getcomposer.org/download/).
+
+2. Run the following command from the directory containing `composer.json`:
+
+       php composer.phar install
+
+### Provide required credentials
+
+Both `process-card.php` and `index.html` have values near the top of the file
+that you need to replace with various credentials associated with your application.
+If you're just testing things out, it's recommended that you use your _sandbox_
+credentials for now. See
+[this article](https://docs.connect.squareup.com/articles/using-sandbox/)
+for more information on the API sandbox.
+
+You can `grep` for `REPLACE_ME` to find all of the fields to replace.
+
+
+## Running the sample
+
+From the sample's root directory, run:
+
+    php -S localhost:8000
+
+You can then visit `localhost:8000` in your browser to see the card form.
+
+If you're using your sandbox credentials, you can test out an valid credit card
+transaction by providing the following card information in the form:
+
+* Card Number 4532 7597 3454 5858
+* Card CVV 111
+* Card Expiration (Any time in the future)
+* Card Postal Code (Any valid US postal code)
+
+**Note that if you are _not_ using your sandbox credentials and you enter _real_
+credit card information, YOU WILL CHARGE THE CARD.**
