How can error reporting and debugging tools be effectively utilized in PHP to troubleshoot form submission problems?

When troubleshooting form submission problems in PHP, error reporting and debugging tools can be effectively utilized to identify and fix any issues. By enabling error reporting and using tools like var_dump() or print_r() to display form data, developers can pinpoint where errors are occurring. Additionally, using tools like Xdebug can help trace the flow of the code and identify any logic errors.

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Display form data for debugging
var_dump($_POST);

// Use Xdebug to trace code flow
// Example: xdebug_start_trace('trace_output');
// Code logic here
// Example: xdebug_stop_trace();
?>
