jQuery:
$(function() { $.post('some_script.php', { width: screen.width, height:screen.height }, function(json) { if(json.outcome == 'success') { // do something with the knowledge possibly? } else { alert('Unable to let PHP know what the screen resolution is!'); } },'json');});
PHP(Somescript.php)
<?php// For instance, you can do something like this:if(isset($_POST['width']) && isset($_POST['height'])) { $_SESSION['screen_width'] = $_POST['width']; $_SESSION['screen_height'] = $_POST['height']; echo json_encode(array('outcome'=>'success'));} else { echo json_encode(array('outcome'=>'error','error'=>"Couldn't save dimension info"));}?>

<?php session_start();if(isset($_SESSION['screen_width']) AND isset($_SESSION['screen_height'])){ echo 'User resolution: ' . $_SESSION['screen_width'] . 'x' . $_SESSION['screen_height'];} else if(isset($_REQUEST['width']) AND isset($_REQUEST['height'])) { $_SESSION['screen_width'] = $_REQUEST['width']; $_SESSION['screen_height'] = $_REQUEST['height']; header('Location: ' . $_SERVER['PHP_SELF']);} else { echo '<script type="text/javascript">window.location = "' . $_SERVER['PHP_SELF'] . '?width="+screen.width+"&height="+screen.height;</script>';}?>
