Hola buenas,

Estoy tratando de hacer un script que haga lo siguiente:

$string='el foro de www.foro.elhacker.net es un foro muy bueno y su pagina web es
www.elhacker.net y con http es http://elhacker.net o http://www.elhacker.net';
 
$stringformateada = formatearurls($string);
 
echo $stringformateada;

Y esto tendria que devolver:


Como veis hay varios formatos de url... por eso necesito un script bastante completo y de momento he sido incapaz de hacerlo....

EDITO: ya tengo el script y funciona a la perfeccion lo pongo por si alguien lo busca algun dia xD...

<?php

* to that URL
* - Goes through the given string, and replaces www.xxxx.yyyy[zzzz] with an HTML <a> tag linking
* to http://www.xxxx.yyyy[/zzzz]
* - Goes through the given string, and replaces xxxx@yyyy with an HTML mailto: tag linking
* to that email address
* - Only matches these 2 patterns either after a space, or at the beginning of a line
*
* Notes: the email one might get annoying - it's easy to make it more restrictive, though.. maybe
* have it require something like xxxx@yyyy.zzzz or such. We'll see.
