[SOLVED] How To Check String For Digits

[refiking]

I get a $player_user variable in the form of $_GET and I need to check to see if there are any digits in it.  How can I go about doing that?

Try:

 

$player_user = $_GET['player_user'];

if (ereg("[0-9]*", $player_user))
{
    print "Digits found!";
}
