Re: Regular expression question

What is $num going to be? A number? So how do you determine where that number ends and where there shouldn't be another number in front of it...are there any restrictions on the size of $num? say $num is 51 then you're saying that you want to match 51:: but not 151:: however, what if $num is 151? see what i mean? ----- Original Message ----- From: "Leon Mergen" <leon@blazebox.com> To: <php-general@lists.php.net> Sent: Friday, November 09, 2001 1:53 PM Subject: [PHP] Regular expression question > Hello, > > I have a little question regarding regular expressions...
