Program | resolution | display This tutorial belongs to the original, reproduced please indicate the Web page teaching network

Today, we made a browser to display the screen resolution of the PHP code, I hope you use it, have any questions please go to the forum post discussion.

First create a new file named: resolution.php the contents of the code are as follows: ( Note: The file name extension must be. PHP is not. HTML)

<script language= "JavaScript" >
<!--
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_res=" + screen.width + "x" + screen.height;
var The_cookie = The_cookie + "; expires=" + the_cookie_date;
Document.cookie=the_cookie

location = ';
}

function checkres (width, height) {
if (width!= screen.width | | height!= screen.height) {
Writecookie ();
} else {
return true;
}
}
-->
</script>


<script language= "JavaScript" >
<!--
Checkres (1024, 768);
-->
</script>

Next, put the following code where you want to display the visitor's display resolution information! (The following code, of course, is also placed in the extension. PHP file)

<?php
$callget_res_page_name = $request_uri;
$globals[callget_res_page_name] = $callget_res_page_name;
Include ("resolution.php");
echo $screen_width. " X ". $screen_height." Is your screen resolution. ";
?>

Note: $ should be half a corner.
