dreaded regexp's

[Da Warriah]

i just recently learned regexps, and so im having a bit of trouble with them...im trying to make a PHP browser detector, and i have most of it worked out, but im trying to figure out a way to find the difference between netscape and mozilla...heres Netscape's user agent, um, thing:

Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:1.0.1) Gecko/20020823 Netscape/7.0

and here's Mozilla (Firebird)'s:

Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:1.4b) Gecko/20030516 Mozilla Firebird/0.6

now how do i use a regexp to determine whether a browser is mozilla or not, either searching for "Mozilla" twice, or making sure "Netscape" and "MSIE" are not listed inside the user agent...thanx for the help

cmon people, does no one know regular expressions or something? all i need is to know how to get Mozilla to return true, and Netscape to return false...

Just search through looking for the string "Netscape":

<?PHP
$browser = $_SERVER["HTTP_USER_AGENT"];
if (preg_match("/Netscape/",$browser)) {
    echo "The browser is Netscape";
}
else {
    echo "The browser is not Netscape";
}
?>

Here's a bit more of a comprehensive browser detection scheme. It works in all the browsers I tested in (IE6, NN7, NN4.7, Mozilla 1.2, and Opera 7)

<?PHP
$browser = $_SERVER["HTTP_USER_AGENT"];
if (preg_match("/MSIE/", $browser)) {
    if (preg_match("/Opera/", $browser)) {
        $brs = "Opera";
    }
    else {
        $brs = "Internet Explorer";
    }
}
else if (preg_match("/Mozilla/", $browser)) {
    if (preg_match("/(Netscape|NE)/",$browser)) {
        $brs = "Netscape";
    }
    else {
        $brs = "Mozilla";
    }
}
else {
    $brs = "unknown";
}
echo "The browser is: ".$brs;
?>

hey thanx, i guess i just didnt think of it that way...i was thinking of differences between the two, when all i needed was the fact that it wasnt one, so it was the other...

*smacks head*
