Ereg v PHPju ne dela!?

Imam takle program:

$forbiden_browsers = array ("TridentSpider", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 4.0; Q312461)", "Googlebot", "ia_archiver", "Openbot");

function check_browser ($item,$key,$users_browser) {
if (ereg ($item, $users_browser)) {
echo("UJEMANJE!");
}
}

// Check it...
reset ($forbiden_browsers);
@array_walk ($forbiden_browsers, 'check_browser', $HTTP_USER_AGENT);

In zdaj fora... VEM, da imam browser z UA = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 4.0; Q312461)"

Ampak ta program mi ne izpiše UJEMANJE!

Kje je napaka???
