How can PHP debugging be effectively done when processing posted form data?

When processing posted form data in PHP, debugging can be effectively done by using the `var_dump()` function to inspect the contents of the `$_POST` array. This allows you to see the data being sent from the form and troubleshoot any issues with processing it. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    var_dump($_POST);
    // Process the form data here
}
?>
