PHP ereg problem

Question

I upgraded to PHP 5.3 and i got the error: ereg has been deprecated.

What can i use to replace this??

function CheckIfAlphaNumberic($text) {
    if (ereg('[^A-Za-z0-9]', $text)) {
        unset ($text);
    }
    return $text;
}

function CheckIfAlphaNumberic($text){
    if (preg_match('#[^A-Za-z0-9]#', $text)) {
        unset ($text);
    }
    return $text;
}

Furthermore, you may use return null; instead of unset ($text);

See what it says on the php site:

It recommends using preg_match()

+1 Though next time please just quote the text (by preceding it with an `>`) instead of inserting an image :) It's pretty hard to read what the image says as it is resized. – NikiC Jun 16 '11 at 19:59
