Preg match a URL but include curly brackets

[ukweb]

Hi all

 

I'm quite a competent PHP coder but where it comes to preg_match I prefer to be ignorant, because I can't get my head around the patterns.

 

Basically, I'm working with a script that someone else has written, and I'm coming across problems because the URL that is being validated sometimes has curly brackets '( )' in it (these are image file names generated by an internal system). I have the pattern, how do I modify this to allow curly brackets? On some occasions, the urls have just the opening or just the closing, so its never the complete set.

 

if someone could give me an indication with this, because I'm clueless! Thanks in advance!

pattern:

	$pattern = '/^(([\w]+?\/\/)?(([\d\w]|%[a-fA-f\d]{2,2})+([\d\w]|%[a-fA-f\d]{2,2})+)?@)?([\d\w][-\d\w]{0,253}[\d\w]\.)+[\w]{2,4}(:[\d]+)?(\/([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)*(\?(&?([-+_~.\d\w]|%[a-fA-f\d]{2,2})=?)*)?(#([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)?$/';
