Regex links

How do I change http://www.whatever.com into [<a href=http://www.whatever.com>link</a>] ?

(For use in a shoutbox-type-thing)

Thanks

Here is a regex that will change

www.google.com to [<a href="http://www.google.com" target="_blank">]

http://www.google.com to [<a href="http://www.google.com" target="_blank">]

and [e-mail] to [<a href="mailto:[e-mail]">[e-mail]</a>]

Hope it is helpful.

$text = preg_replace("#([\n ])([a-z]+?)://([^, \n\r]+)#i", "\1<a href=\"\2://\3\" target=\"_blank\">\2://\3</a>", $text); // Link with http

$text = preg_replace("#([\n ])www.([a-z0-9-]+).([a-z0-9-.\~]+)((?:/[^, \n\r]*)?)#i", "\1<a href=\"http://www.\2.\3\4\" target=\"_blank\">www.\2.\3\4</a>", $text); // Link without http

$text = preg_replace("#([\n ])([a-z0-9-_.]+?)@([^, \n\r]+)#i", "\1<a href=\"mailto:\2@\3\">\2@\3</a>", $text); // E-mail

If for some reason the BB screws the regex, here is a text file with it.
