PHP Newbie - RegEx

Hi,

I'm having trouble doing a simple regex in PHP and wonder if anyone can
help?

Can someone tell me how I find out if a variable contains a digit? I have a
script that is passed either a digit or URL's. If the variable contains a
digit, I want the script to extract info from a database, else if it is a
URL, go to the URL.

I've tried this, amongst other things and just cannot figure it out....

if  ($ID =~ /[0-9]/) {
do this
} else {
do this
}

I hope someone can help.

ATB,

Bill.
