Нужна функция для преобразование Url в ссылку

[Rave]

Сабж... в RegEx не силен

может пояснишь, а? или я туп, или третьего не дано.

Я так понял, что речь идет о превращении текст http://www.foo.bar в <a href="http://www.foo.bar">http://www.foo.bar</a>.

Не найти готовый код -- признак тяжкой лени.

Внатуре, внатуре...
А скопировать код, блин трудно!

Сам на свой вопрос отвечаю.
$msg = preg_replace("/(http|ftp)(s)?\\/\\/)((\\w|\\.)+)(\\/)?(\\S+)?/i", "<a href=\"\\0\" target=\"_blank\">\\0</a>", $msg);
