Stripe PHP bindings

You can sign up for a Stripe account at https://stripe.com.

Requirements

PHP 5.3.3 and later.

Composer

You can install the bindings via Composer. Run the following command:

composer require stripe/stripe-php

To use the bindings, use Composer's autoload:

require_once('vendor/autoload.php');

Manual Installation

If you do not wish to use Composer, you can download the latest release. Then, to use the bindings, include the init.php file.

require_once('/path/to/stripe-php/init.php');

Dependencies

The bindings require the following extension in order to work properly:

curl, although you can use your own non-cURL client if you prefer
json
mbstring (Multibyte String)

If you use Composer, these dependencies should be handled automatically. If you install manually, you'll want to make sure that these extensions are available.

Getting Started

Simple usage looks like:

\Stripe\Stripe::setApiKey('d8e8fca2dc0f896fd7cb4cb0031ba249');
$myCard = array('number' => '4242424242424242', 'exp_month' => 8, 'exp_year' => 2018);
$charge = \Stripe\Charge::create(array('card' => $myCard, 'amount' => 2000, 'currency' => 'usd'));
echo $charge;

Documentation

Please see https://stripe.com/docs/api for up-to-date documentation.

Legacy Version Support

If you are using PHP 5.2, you can download v1.18.0 (zip, tar.gz) from our releases page. This version will continue to work with new versions of the Stripe API for all common uses.

This legacy version may be included via require_once("/path/to/stripe-php/lib/Stripe.php");, and used like:

Stripe::setApiKey('d8e8fca2dc0f896fd7cb4cb0031ba249');
$myCard = array('number' => '4242424242424242', 'exp_month' => 8, 'exp_year' => 2018);
$charge = Stripe_Charge::create(array('card' => $myCard, 'amount' => 2000, 'currency' => 'usd'));
echo $charge;

Custom Request Timeouts

NOTE: We do not recommend decreasing the timeout for non-read-only calls (e.g. charge creation), since even if you locally timeout, the request on Stripe's side can still complete. If you are decreasing timeouts on these calls, make sure to use idempotency tokens to avoid executing the same transaction twice as a result of timeout retry logic.

To modify request timeouts (connect or total, in seconds) you'll need to tell the API client to use a CurlClient other than its default. You'll set the timeouts in that CurlClient.

// set up your tweaked Curl client
$curl = new \Stripe\HttpClient\CurlClient();
$curl->setTimeout(10); // default is \Stripe\HttpClient\CurlClient::DEFAULT_TIMEOUT
$curl->setConnectTimeout(5); // default is \Stripe\HttpClient\CurlClient::DEFAULT_CONNECT_TIMEOUT

echo $curl->getTimeout(); // 10
echo $curl->getConnectTimeout(); // 5

// tell Stripe to use the tweaked client
\Stripe\ApiRequestor::setHttpClient($curl);

// use the Stripe API client as you normally would

Custom cURL Options (e.g. proxies)

Need to set a proxy for your requests? Pass in the requisite CURLOPT_* array to the CurlClient constructor, using the same syntax as curl_stopt_array(). This will set the default cURL options for each HTTP request made by the SDK, though many more common options (e.g. timeouts; see above on how to set those) will be overridden by the client even if set here.

// set up your tweaked Curl client
$curl = new \Stripe\HttpClient\CurlClient(array(CURLOPT_PROXY => 'proxy.local:80'));
// tell Stripe to use the tweaked client
\Stripe\ApiRequestor::setHttpClient($curl);

Alternately, a callable can be passed to the CurlClient constructor that returns the above array based on request inputs. See testDefaultOptions() in tests/CurlClientTest.php for an example of this behavior. Note that the callable is called at the beginning of every API request, before the request is sent.

Development

Install dependencies:

composer install

Tests

Install dependencies as mentioned above (which will resolve PHPUnit), then you can run the test suite:

./vendor/bin/phpunit

Or to run an individual test file:

./vendor/bin/phpunit tests/UtilTest.php
