Need a regex that matches URLs with/without http:// or www. or http://www. in a text

Question

I've been trying to find a solution myself but I couldnt do it so far (even tried all regexlib.com suggestions), so:

Need a regex that matches URLs like (PHP code):

http://example.com orhttp://www.example.com or www.example.com example.com

Answer 1

How about this?

(www|http:\/\/|https:\/\/)?([.[:alnum:]-]){0,4}([[:alnum:]-]+.)([[:alnum:]_-].?)([[:alpha:]]){0,3}

Answer 2

I've been trying to use this one (catch http://(optional)www.example.com/path/otherpath):

$regex = "/(((ftp|https?):\/\/www.)|(www.)|(http:\/\/))([\d\w-.]+?)+(:\d+)?(\/([\w\/,=]*(\?\S+)?)?)?/";

but it's not enough.

Still missing the example.com. Any suggestion?
