How can proper debugging techniques help in identifying issues with PHP scripts, especially in form handling?

Proper debugging techniques such as using var_dump(), print_r(), and error reporting can help in identifying issues with PHP scripts, especially in form handling. By carefully examining the output of these debugging tools, developers can pinpoint errors in the code, such as incorrect variable values or syntax errors, and make the necessary corrections.

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

// Debug form data
var_dump($_POST);
print_r($_POST);

// Your form handling logic here
?>
