browser detection

can PHP be used for it?

[mylungsarempty]

I'm trying to use a conditional to present one line of HTML if the user is on MSIE, or another if the user is on netscape... i'm having some problem with it -- i dont understand why -- but if PHP can do the same thing i'll probably have better luck with it. Does php detect browsers? What is that code

[seomike2003]

$_SERVER['HTTP_USER_AGENT']

$_SERVER['HTTP_USER_AGENT']

Check out the docs [es.php.net], they should sort you out.

You can get the information you need from the server variable "HTTP_USER_AGENT". A quick and dirty would be something like this:

$agent = $_SERVER["HTTP_USER_AGENT"];
if ( strstr($agent,"MSIE") )
echo "you are using Internet Explorer";

However, some browsers allow the end user to change the user agent string.
I hope this helps.

also take a look at get_browser() [ca.php.net]

Try:

$agent = getenv("HTTP_USER_AGENT");

I use phpSniff which is very good. But it returns far more information than I need, so if anyone knows of a simpler version which just returns browser type and version please shout.
