PEAR::DB uses this method - I'm seeing a million errors on sites that have
updated to latest CVS version.

You're forced to i use this method if you want to link a resource back to
it's creation information.

If you have an array of IPs, and you create an array of resources from each
IP, a third array linking the IP back to the casted interger value of the
resource is required if you want to get the IP back. (This is very confusing
to write).

Here's an example:

<?php
$servers[] = "139.134.253.11:27025";
$servers[] = "203.114.130.7:27015";

foreach ($servers as $server)
{
    list($ip, $port) = explode(':', $server);
    $sock = @fsockopen("udp://" . $ip, $port, $errno, $errstr, 1);
    if ($sock !== false)
    {
        $sockets[] = $sock;
        // Create an array so we can link the socket back to the server
        $server_keys[$sock] = array_search($server, $servers);

    }
}

while (stream_select($r, $w = null, $e = null, 0, calctimeout($maxtime,
$starttime)) !== 0)
{
    ++$i;
    foreach ($r as $socket)
    {
        $response = stream_get_contents($socket);
        // Put the response into an array with the original IP as the key
        $results[$server_keys[$socket]][] = $response;
    }
}
?>

I hope that demonstrates the purpose properly.

Ofcourse this method can still be used, it just requires an extra cast
(which is a cleaner solution anyway).

Aidan
