Perhaps not the most efficient way, but one that is quite simple and provides for easy control over characters used in the generated strings/passwords:

<?php
	function generateCode($length=6) {
		$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPRQSTUVWXYZ0123456789";
		$code = "";
		while (strlen($code) < $length) {
			$code .= $chars[mt_rand(0,strlen($chars))];
		}
		return $code;
	}
?>
