title: PHP Issue - function output is 000
body: <p>I've been trying to make a CLI application that logs Yahoo! messenger login dates/times for certain users using a third party, but this isn't really getting anywhere. Even though checking iself works when used individually, it does not seem to when using the while &amp; foreach too. checkAvailability outputs "000". Could anyone please fix this and perhaps optimize it?</p>
