Curly Bracket Delimeters.

Posted on 16th Feb 2014 07:03 pm by admin

I'd always believed that the starting and ending delimeters in preg_ functions had to be the same character, but recently discovered that you can use the curly brackets.

Example:
Code: [Select]if(preg_match('{[0-9]}', $input)) {
I was just wondering if there was any disadvantage/advantage of using this method?
