[SOLVED] Can I use regex to make this more compact?

[revraz]

Can I use a replace function to make this better?

 

$rdate = "12/31/2007-14:00";

$rdate = str_replace ("-", "", $rdate);
$rdate = str_replace ("/", "", $rdate);
$rdate = str_replace (":", "", $rdate);

echo $rdate; //123120071400

 

I basically want to strip everything non numeric and get a 12 digit number.

$rdate = preg_replace('%\D%','',$rdate);

Thanks a ton.  I really need to learn more about regex, everytime I read how it works I get a headache.
