I've been using this function, it works for me

function AutoLinkUrls($str,$popup = FALSE){
    if (preg_match_all("#(^|\s|\()((http(s?)://)|(www\.))(\w+[^\s\)\<]+)#i", $str, $matches)){
        $pop = ($popup == TRUE) ? " target=\"_blank\" " : "";
        for ($i = 0; $i < count($matches['0']); $i++){
            $period = '';
            if (preg_match("|\.$|", $matches['6'][$i])){
                $period = '.';
                $matches['6'][$i] = substr($matches['6'][$i], 0, -1);
            }
            $str = str_replace($matches['0'][$i],
                    $matches['1'][$i].'http'.
                    $matches['4'][$i].'://'.
                    $matches['5'][$i].
                    $matches['6'][$i].''.
                    $period, $str);
        }//end for
    }//end if
    return $str;
}//end AutoLinkUrls
