Preg replace in textarea links

Question

What can I do to play these link on textarea

Ex:

http://link1.com/embed/código/nomepagina 
http://link2.com/v/código/nomepagina 
http://link3.com/e/código/

And he returns me only

http://link1.com/código/ 
http://link2.com/código/ 
http://link3.com/código/

Taking the code only and formatting leaving the way up.

I created this regex that meets in this case you made:

(http:\/\/\w+\.\w+\/)(\w+)\/(\w+)\/(.+)?

 ^ .... grupo do link        ^.... grupo do código

Then take the elements of each group that will be used and join.

Would that be the code:

$str = "http://link1.com/embed/codigo/nomepagina 
        http://link2.com/v/codigo/nomepagina 
        http://link3.com/e/codigo/";

$str = preg_replace('/(http:\/\/\w+\.\w+\/)(\w+)\/(\w+)\/(.+)?/', '$1$3 ', $str);
                  //                                              ^ aqui haverá a junção

Exit:

http://link1.com/codigo http://link2.com/codigo http://link3.com/codigo

As it is a url I removed from código the accent on the ó

Editing

For subdomains and other types of domains I made the code like this:

$str = preg_replace('/(http:\/\/|https:\/\/)?([\w\.]+\/)([\w-_]+\/)?([\w-_]+)\/?(.+)?/', '$2$4 ', $str);
