Determining Mac Platform

new7media

I use getenv("HTTP_USER_AGENT") to determine between IE and other browsers. This works perfectly fine for a small site that I've put together. here's my code:

if (!ereg("MSIE", getenv("HTTP_USER_AGENT"))) {
$header = 'not_ie.php';
} else {
$header = 'ie.php';
}
include("$header");

Now I need to determine platform -- specifically I need to know when a Macintosh is accessing the site. I tried the following code
but when I pull up a page using a Mac (a new I-book w/ OS X if that makes a difference) apparently the script doesn't do the trick because I get "This ain't a Mac."

if (ereg("Mac", getenv("HTTP_USER_AGENT"))) {
echo ("This is a Mac.");
} else {
echo ("This ain't a Mac.");
}

There must be a better way to determine platform. Also, what I'm shooting for is to first determine whether or not the user is on a Mac, and then whether or not the user is using IE. Is there any particular concern this raises in writing my if/else statement?

Appreciate any help!

check out devedge.netscape.com

more specifically

http://devedge.netscape.com/viewsource/2002/browser-detection/

they have a javascript browser-sniffer which detemines many thigns from the UserAgent.... yeah i know you want this in php... however.. the logic should be the same especially since php has the intVal() function... so a quick conversion should be none to difficult

I realized that I used "ereg()" rather than "eregi()" in my if/else statement so that only "Mac" was being qualified. I revised to use eregi() wh/ is case insensitive, and so far testing seems to be working ok.

if (eregi("mac", getenv("HTTP_USER_AGENT"))) {
echo ("This is a Mac.");
} else {
echo ("This ain't a Mac.");
}

Just thought I'd post that for others to see. Thanks!
