]]> I think there is no way yet to find out screen resolution with PHP. hehehe.
If I am wrong please correct me.
But yet we can trick it to be happen ;-)
If not then how can we be developers. Right!

With javascript we find out screen resolution of PC. Store it in a cookie and display it with PHP.
Coool…eh! Fine, lets just do it.

<script LANGUAGE="javascript">
width = screen.width;
height = screen.height;
document.write("<b>You're set to "+width+ "X" +height+"</b>")
</script>
<?php
$yo=$_GET['width'];
echo $yo;
?>

For head section of webpage.

<?
if(isset($HTTP_COOKIE_VARS["users_resolution"]))
$screen_res = $HTTP_COOKIE_VARS["users_resolution"];
else //means cookie is not found set it using Javascript
{
?>
<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 = 'screen.php';
}
//-->
</script>
<?
}
?>

Body section of webpage. Display the screen resolution.

<?php
echo "Your screen resolution is set at ". $screen_res;
?>

]]> Cookies were invented to allow webmaster’s to store information about the user and their visit or other information on the user’s computer. Cookies are not privacy risk. All of the “trustworthy” websites use cookies.

Creating Cookie – Last Visit Script

<?php
//Calculate 60 days in the future
//seconds * minutes * hours * days + current time
$inTwoMonths = 60 * 60 * 24 * 60 + time();
setcookie('lastVisit', date("G:i - m/d/y"), $inTwoMonths);
?>

Retrieving Cookie

If your cookie hasn’t expired yet, you can retrieve it from the user’s PC using the named $_COOKIE associative array. The name of your stored cookie is the key and will let you retrieve your stored cookie value!

<?php
if(isset($_COOKIE['lastVisit']))
	$visit = $_COOKIE['lastVisit'];
else
	echo "You've got some stale cookies!";
 
echo "Your last visit was - ". $visit;
?>
