What exactly is it looking for here. I don't see what the criteria are.

PHP Code:

$re = "/(www\.)?(\w*[^\.])(\.[a-z]{2,3})/"; 


From what I can guess it's searching for "www", and then any combination of 2 letters after a " . " ?

Sorry I did not know there was a question for me here.
regexp is hard to use at once but easy to implement if you know what you want to reach.
especially if know what conditions / quantifiers must be used.

For that regexp, I gave an example of what that regexp would match, mainly:
domain.com OR domain.co

$re = "/(www\.)?(\w*[^\.])(\.[a-z]{2,3})/";

(www\.)? means we could have www or not.

consider this list of urls

domain.com
www.domain.com
http://www.domain.com/vb/images/page.php
http://www.domain.co.uk/vb/image/pages/page.php


as you see, not interested in the full URL.

check this, might help a lot:

and must know if there is a match, how many found, and how to iterate through the result array.

sorry for the late reply, better later than never though
