How can modularizing a PHP script help in debugging and maintaining code, especially when dealing with email functionality?

Modularizing a PHP script can help in debugging and maintaining code by breaking down the functionality into separate modules or classes. This makes it easier to isolate and identify issues, as well as make changes or updates without affecting other parts of the code. When dealing with email functionality, modularizing can allow for better organization of email-related code, making it easier to troubleshoot and enhance email features. 

// Example of modularizing email functionality in PHP

// email.php
class Email {
    public function sendEmail($to, $subject, $message) {
        // code to send email
    }

    public function formatEmail($message) {
        // code to format email message
    }
}

// main.php
require_once 'email.php';

$email = new Email();
$to = 'recipient@example.com';
$subject = 'Testing modularized email functionality';
$message = 'This is a test email message.';

$formattedMessage = $email->formatEmail($message);
$email->sendEmail($to, $subject, $formattedMessage);
