Great regex, thanks ! Small thing : the '-' (dash) is missing - URL like this fails (http://web5.uottawa.ca/admingov/reglements-methodes.html)

it's also missing left parenthesis, right parenthesis, and comma.

Took me a few min to track this down on Google but it was exactly what I was looking for. Thank You.

Does this work with links that do not have the "http" or "https" in front of it. like ubuntu.com for example?

I improved the regex given here, to take into account your comments : pregreplace('@((https?://)?(\w+.[-\w.]+)+\w(:\d+)?(/([-\w/.](\?\S+)?)?))@', '$1', $text);

Now with this regex, the links can be without any http:// or https:// block (like www.exemple.com) and can have multiple /folder/subfolder/file.htm after the domain, and finally "-" are considered as part as a standard URL.

Thanks for the first regex that helped me a lot find this one ! I hope mine will help the others.

just replace the regex by '@((https?://)?(\w+.[-\w.]+)+\w(:\d+)?(/(-\w/.?)?))@' because in my last post, some characters are missing because of misinterpretation...

Well it also removes the underscores... So I posted my contribution here : http://snipplr.com/view/36991/improvement-of-url-interpretation-with-regex/
