A simple script for checking what message queues are in use on a [presumably new] server environment.
Run with php-cli
<?php
$k = 0;
while (true) {
echo $key,"...\r";
if (msg_queue_exists($key))
echo "\r",$key,'::Exists',"\n";
$key++;
}
?>

A workaround for those not yet running 5.3 on *nix:
<?php
function queue_exists($key) {
if(function_exists("msg_queue_exists")) {
return msg_queue_exists($key);
} else {
$aQueues = array();
exec("ipcs -q | grep \"^[0-9]\" | cut -d \" \" -f 1", $aQueues);
if(in_array($key,$aQueues)) return true;
else return false;
}
}
?>
Maybe a bit slow and kludgey, but it works.
