PHP-PayPal-IPN

A PayPal Instant Payment Notification (IPN) class for PHP 5.

Use the PaypalIPNListener class in your PHP IPN script to handle the encoding of POST data, post back to PayPal, and parsing of the response from PayPal.

Service for Laravel

'Fahim\PaypalIPN\PaypalIPNServiceProvider',

Use case

Features

• Switch between live and sandbox by setting the use_sandbox property.
• Supports both secure SSL and plain HTTP transactions by setting the use_ssl property (SSL is recommended).
• Supports both cURL and fsockopen network libraries by setting the use_curl property (cURL is recommended).
• Verifies an HTTP "200" response status code from the PayPal server.
• Get detailed plain text reports of the entire IPN using the getTextReport() method for use in emails and logs to administrators.
• Throws various exceptions to differentiate between common errors in code or server configuration versus invalid IPN responses.

Getting Started

This code is intended for web developers. You should understand how the IPN process works conceptually and you should understand when and why you would be using IPN. Reading the PayPal Instant Payment Notification Guide is a good place to start.

You should also have a PayPal Sandbox Account with a test buyer account and a test seller account. When logged into your sandbox account there is an IPN simulator under the 'Test Tools' menu which you can used to test your IPN listener.

Once you have your sandbox account setup, you simply create a PHP script that will be your IPN listener. In that script, use the IpnListener() class as shown below. For a more thoroughly documented example, take a look at the example/ipn.php script in the source code.

Documentation

Documentation has not been generated yet, but, there are phpDocumentor style docstrings (comments) throughout ipnlistener.php which explain the important public properties and methods.

I have also written a more in-depth IPN tutorial on my blog: PayPal IPN with PHP

Known Issues

Problem

The processIpn() method throws the following exception:

cURL error: [52] GnuTLS recv error (-9): A TLS packet with unexpected length was received.

Solution

When cURL is compiled with GnuTLS the call to PayPal will fail if the SSL version is not explicitly set as a cURL option. Set the force_ssl_v3 property to force SSL 3:

_Note: force_sslv3 is now true by default

Problem

 PHP Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION 
 cannot be activated when in safe_mode or an open_basedir is set in ...

Solution

If you need PHP safe mode, you can disable CURLOPT_FOLLOWLOCATION using the follow_location property.

_Note: followlocation is now false enabled by default

Example Report

Here is an example of a report returned by the getTextReport() method. Create your own reports by extending the IpnListener() class or by accessing the data directly in your ipn script.
