PHP: function that will replace textual URLs with HTML links, this also works for email addresses.

replace.php

<?php
function replace_links( $text ) 
{    
	$text = preg_replace('#(script|about|applet|activex|chrome):#is', "\\1:", $text);

	$ret = ' ' . $text;
	
	// Replace Links with http://
	$ret = preg_replace("#(^|[\n ])([\w]+?://[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href=\"\\2\" target=\"_blank\" rel=\"nofollow\">\\2</a>", $ret);
	
	// Replace Links without http://
	$ret = preg_replace("#(^|[\n ])((www|ftp)\.[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a href=\"http://\\2\" target=\"_blank\" rel=\"nofollow\">\\2</a>", $ret);

	// Replace Email Addresses
	$ret = preg_replace("#(^|[\n ])([a-z0-9&\-_.]+?)@([\w\-]+\.([\w\-\.]+\.)*[\w]+)#i", "\\1<a href=\"mailto:\\2@\\3\">\\2@\\3</a>", $ret);
	$ret = substr($ret, 1);
	
	return $ret;
}

Thank you, nice but some urls without http(s) and without www are not identified as links.
Example: georisques.gouv.fr
