I had to modify this a bit to work for me.

**`#!/usr/bin/env php

&1 | awk {'print $1,$2'} | grep '*:'| sed 's/^..//'"; $vhosts = shell_exec(sprintf("%s %s", $binary, $command)); $vhosts = explode("\n", trim($vhosts)); $results = array(); foreach($vhosts as $vhost) { $x = explode(' ', $vhost, 2); $new_entry['{#SERVERNAME}'] = $x[1]; $new_entry['{#SERVERPORT}'] = $x[0]; $results['data'][] = $new_entry; } return $results; }`**
