How can PHP developers troubleshoot issues with form submissions not functioning correctly?

Issue: To troubleshoot form submission issues in PHP, developers can start by checking the form action attribute to ensure it is pointing to the correct PHP file. They should also verify that the method attribute matches the PHP code handling the form submission (POST or GET). Additionally, developers can use var_dump($_POST) or var_dump($_GET) to inspect the data being submitted and debug any potential issues. 

<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {
    // Check if form is submitted
    var_dump($_POST); // Debug form data
    // Add code to process form submission
}
?>
