Simulates paypal Ipn request for a local Magento store

magento_simulate-paypal-ipn.php

<?php
// SIMULATE PAYPAL IPN LOCALLY
//
// Sometimes you need to test on your local host and this can be difficult due
// to IP routing issues.  Use this code on your local machine to simulate the
// same process that the sandbox IPN simulator does when posting to your URL.
//
// Run this code in command line or via the browser. It will post IPN data just
// like Paypal would.  If the code you've written to process your IPN data
// posts back to the sandbox, it should come back as valid.

// Put the full url to test in $paypal_url, include file extensions if necessary
$paypal_url = 'http://dev.yourstore.com/paypal/ipn';   // IPN listener to test
