如何确定在php中使用的screen.width的变量window.width？

Question

I need to know the screen size in jquery or javascript and I need this value is printed on a php variable that will determine whether or not an item is displayed.

var width = $(window).width();  

if (width <= 1024) {
   ///// How can I set a variable here and use it with php?
}

Thanks!

mate, you never get the window width from your php code, php code is executing on your web server, you can only get your window size from javascript which is working on user's browser, you just need find a way sending the width you got from js to your php code, that's it !

sample code :

function myJavascriptFunction() { 
  var javascriptVariable = "John";
  window.location.href = "YOURPHPFILE.php?name=" + javascriptVariable; 
}
