How can debugging techniques be applied to troubleshoot issues with PHP form submissions?

Issue: When troubleshooting issues with PHP form submissions, one common technique is to use var_dump() or print_r() functions to inspect the data being submitted by the form. This can help identify any errors in the data being passed to the PHP script and make it easier to pinpoint where the issue lies. 

<?php
// Debugging form submissions
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    var_dump($_POST); // Inspect the data being submitted
    // Additional debugging steps can be added here
}
?>
