I only know abit about it, regular expressions aren't my strong point.

@dontpanic: tofind is the search code, like survivor and replacement is the code to replace it with, I just used those as they were shorter. The ^ before the bracket should negate whats in it so if it matches the first part, but not the second then it does the replacement. At least thats how you want it too work.

Right. Now down to business. I will see what I can come up with given this great start! :)

Now I'm certain the above, won't work , however its along those lines ;)

NTLDR, this may be close, but PHP is seeing the

Code:

</a>

as an unknown "a" modifier.

PHP Code:


		
			
$var = preg_replace('/(tofind)^(<a href="\S">tofind<\/a>)/i', 'replacement', $var);

Whoops, forgot the \ before the \/a that will solve that error :)

I figured that. :)

Anyhow, I have inserted my information into the code as seen:

Code:

$post['message'] = preg_replace('/(70-292)^(<a href="\S">70-292<\/a>)/i', '<a href="http://www.mcseworld.com/a/1932266569/" target="_blank">\\1</a>', $post['message']);

This works great in the fact that it causes no errors. This does not work great in the fact that it doesn't replace anything. :ermm: Now we know why these regex's are such a pain in the butt!

I'll get back on this shortly. Gotta go do some paying work now.
