note 20757 deleted from function.ereg-replace by sander

I realized that the second ereg_replace would not work, because it creates a link like "http:// www.php.ch" wich will not work. please use this one: $string = preg_replace("([ |\n]([a-zA-Z1-9\-_\.]+\.[a-zA-Z1-9\-_]+\.[a-z]{2,3}))", " <a href=\"http://\\1\" target=\"_blank\">\\1</a>", $string); It will search for a space but will not include it in the url, but displaying one in front of the link. if your url was after a new line, the space will be removed.
