Works for me:

<?php
$foo = array('moon' => 'stars', 'test' => null);
var_dump(in_array('stars', $foo)); // true
var_dump(in_array(null, $foo)); // true
var_dump(in_array('not-in-array', $foo)); // true
?>

However, if you try:

<?php
in_array('foo', null);
?>

You will get your wrong datatype error. In that case, you should check
if $aidlook itself is null (or a non-array), like such:

<?php
if (!is_array($aidlook)) $aidlook = array($aidlook);
?>
