So you want to remove certain characters from a string? I've said it
before and I'll say it again: why do people insist upon using regular
expressions to do things that str_* functions can handle in a much
easier and faster way? Not only will it run faster, but you'll save
yourself from exactly the kind of headaches you're experiencing.

$chars = array('&', "'", '/', '_', '-');
$output = str_replace($chars, '', $string);
