How can PHP debugging techniques help identify errors in mail form scripts?

PHP debugging techniques can help identify errors in mail form scripts by allowing developers to track variables, check for syntax errors, and log error messages. By using tools like error_reporting(), var_dump(), and print_r(), developers can pinpoint the exact location of the error in the code and fix it accordingly.

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Code for sending email

if (mail($to, $subject, $message, $headers)) {
    echo 'Email sent successfully';
} else {
    echo 'Email sending failed';
}
?>
