How can PHP developers troubleshoot and debug issues with form submission?

To troubleshoot and debug issues with form submission in PHP, developers can start by checking for errors in the form validation process, ensuring that all necessary form fields are being submitted correctly, and verifying that the form data is being processed accurately. They can also use PHP functions like var_dump() or print_r() to display the form data and identify any potential issues. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Check if form fields are being submitted correctly
    if (isset($_POST['submit_button'])) {
        // Process form data
        $name = $_POST['name'];
        $email = $_POST['email'];
        
        // Debug form data
        var_dump($_POST);
        
        // Additional processing logic
    } else {
        echo "Form submission error: Submit button not detected.";
    }
}
?>
