How can the use of Firebug help in debugging form submission issues in PHP?

To debug form submission issues in PHP, Firebug can be used to inspect the network requests and responses, including form data being sent to the server. This can help identify any errors in the form data being submitted or in the PHP script processing the form. By analyzing the data being sent and received, developers can pinpoint the source of the issue and make necessary corrections. 

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Check if form data is being submitted correctly
    if (isset($_POST['submit_button'])) {
        // Process form data here
    } else {
        // Debug form submission by checking the data sent using Firebug
        echo '<script>alert("Form submission error. Check Firebug for details.")</script>';
    }
}
