PHP: Newbie question...

Hi PHPies, Firstly to say that I've got PHP/MySQL running on my Wintel 98/PWS without any glitches (nothing proud, though) at the very first attempt, even got the php.ini settings without any difficulty. Well, I'm new to PHP and just have a small question (may be I'm missing something). I've got a php program that I want to display the list of all the values that are available in the HTTP_USER_AGENT array. But I believe there's something wrong in the code. Please do have a look at the code and let me know what I'm missing. <the phpcode> <?php function list_array ($array) {

    while (list ($key, $value) = each ($array)) {
        $str .= "<b>$key:</b> $value<br>\n";
    }
    return $str;

} echo "$HTTP_USER_AGENT<hr>\n"; $browser = get_browser($HTTP_USER_AGENT); echo list_array ((array) $browser); ?> </the phpcode> T I A for any words of wisdom. Regards Prem ~~~~~~~~~~~~ premchandran c.v webmaster, www.ciol.com
