How can the use of var_dump() in PHP help troubleshoot issues with form submissions not sending POST variables?

When form submissions are not sending POST variables, it can be challenging to pinpoint the issue. Using var_dump() in PHP can help troubleshoot by displaying the contents of the POST variables, allowing you to see if they are being properly submitted. This can help identify any errors in the form submission process or server configuration. 

<?php

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Use var_dump() to display POST variables
    var_dump($_POST);
    
    // Process form submission
    // Add code here to handle form data
}

?>
