How To Get Screen Resolution


well, with php, you can get and show the screen resolution by using javascript.

the javascript code:
lt;script language="javascript">
<!--
writeCookie();
function writeCookie()
{
var today = new Date();
var the_date = new Date("December 31, 2023");
var the_cookie_date = the_date.toGMTString();
var the_cookie = "users_resolution="+ screen.width +"x"+ screen.height;
var the_cookie = the_cookie + ";expires=" + the_cookie_date;
document.cookie=the_cookie

location = 'test.php';
}
//-->
</script>


the code:
<?php
if(isset($HTTP_COOKIE_VARS["users_resolution"]))
$screen_res = $HTTP_COOKIE_VARS["users_resolution"];


if you want to put it all together, i have created a complete hmtl demo. all you have to do is copy and paste code below into notepade, then save it as wallpaperama.php and upload to your php website, then open it with your browser and it will show you what YOUR screen resolution is.
