How to check if $_GET is empty

Using, "isset" to check if $_GET, will not work.  The function, "isset()", is normally my goto function to check if a variable is empty.  In this case, it will not work.  We need to use the "empty()", function.  

Php code snippet:

<?php

if(empty($_GET) {

   echo "no parameters received";

   exit;  //terminates script early.

}

?>
