browser check

[caislander]

Hi,

I need to add a browser check to forumhome template so I can serve a different header based on browser (specificaly I need to serve a watered down ver of our header if they have NS 4.xx) so I tried adding this the the template

PHP Code:

<?php
function doriteheader() {
    // serve correct header by browser
    global $HTTP_USER_AGENT;

    if (eregi("Mozilla/4.",$HTTP_USER_AGENT)) { // browser is NS4
        return "$footer";

    } else { // other browsers
        return $header;

    }

}
?>

and all that seems to do is display the footer (I used footer in place of my second header so it was easy to see if this worked or not) then some of the php was displayed as plain text then a header. So obviously I did something wrong (so what's new) can someone help me get this correct?

Thanks for your time
