A better (faster) version:
<?php
function in_array ($item, $array) {
    $item = &strtoupper($item);
    foreach($array as $element) {
        if ($item == strtoupper($element)) {
            return true;
        }
    }
    return false;
}
?> 

Noah B, set the 3rd argument to true and everything will wokr fine :) 0 == 'foo' is true, however 0 === 'foo' is not.
