Paypal multiple IPN Help.

[ka0zstyle]

It found several scripts to send an IPN to several servers but I don't know how to configure it for an ot Does anyone help me? It seems simple (for you who are pro xD <3 scripters)

<?php

    ini_set( 'max_execution_time', 0 ); // Do not abort with timeouts
    ini_set( 'display_errors', 'Off' ); // Do not display any errors to anyone
    $urls = array(); // The broadcast session queue

    // List of IPN listener points ** ADJUST THESE TO POINT TO YOUR LISTENERS
    $ipns = array(
            'first' => 'http://www.yourwebsite1.co.uk//paypal/ipn.php',
            'second' => 'http://www.yourwebsite2.co.uk//paypal/ipn.php',
            'third' => 'http://www.yourwebsite3.co.uk//paypal/ipn.php'
        );

    // ** ADJUST THESE CONDITIONS TO FILTER
    if($_POST['txn_type']!='cart') $urls []= $ipns['first']; // Choose this IPN URL if all conditions have been met
    if(isset($_POST['auction_buyer_id'])) $urls []= $ipns['second']; // Choose this IPN URL if all conditions have been met
    $urls []= $ipns['third']; // maybe this one is always sent to

    // Broadcast
    if ( !sizeof($urls) ) $urls = $ipns; // No URLs have been matched
    $urls = array_unique( $urls ); // Unique, just in case

    // Broadcast (excluding IPNs from the list according to filter is possible
    foreach ( $urls as $url ) broadcast( $url );

    header( 'HTTP/1.1 200 OK', true, 200 );
    exit();

    // Perform a simple cURL-powered proxy request to broadcast
    function broadcast( $url ) {

        // Format POST data accordingly
        $data = array();
        foreach ($_POST as $key => $value) $data []= urlencode($key).'='.urlencode($value);
        $data = implode('&', $data);

        // Log the broadcast
        file_put_contents('_logs/'.time().'.'.reverse_lookup( $url ).'-'.rand(1,100), $data);

        $ch = curl_init(); // Initialize

    function reverse_lookup( $url ) {
        global $ipns;
        foreach ( $ipns as $tag => $_url ) {
            if ( $url == $_url ) return $tag;
        }
        return 'unknown';
    }

In my main server I already have my IPN configured perfectly so I already have a notion of how these scripts work .. I am not so at zero, so if someone explains to me "without so many details" I think I can understand thank you very much <3


If I am not mistaken, this script will detect the IPN "Name_item" of paypal and depending on the name of the NAME_ITEM it will send an IPN to the server that corresponds to it, right?
