How can PHP developers effectively access JavaScript variables using $_GET when handling user interactions on a webpage?

When handling user interactions on a webpage, PHP developers can effectively access JavaScript variables using the $_GET superglobal array. To do this, JavaScript variables can be passed to PHP by appending them to the URL as query parameters. In PHP, these variables can then be accessed using $_GET['variable_name']. 

// JavaScript code to pass variable to PHP
<script>
  var jsVariable = "Hello World";
  window.location.href = "process.php?phpVariable=" + jsVariable;
</script>

// PHP code in process.php to access the JavaScript variable
<?php
  $phpVariable = $_GET['phpVariable'];
  echo $phpVariable; // Output: Hello World
?>
