How can debugging techniques in PHP help identify issues with the sender email address not displaying correctly in contact form emails?

Issue: Debugging techniques in PHP can help identify issues with the sender email address not displaying correctly in contact form emails by checking for any errors in the code that handles the email sending process, verifying the email address format, ensuring that the email headers are properly set, and testing the email functionality with different email addresses. PHP Code Snippet: 

// Set sender email address
$sender_email = 'sender@example.com';

// Set additional headers
$headers = 'From: ' . $sender_email . "\r\n" .
    'Reply-To: ' . $sender_email . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

// Send email
$success = mail('recipient@example.com', 'Subject', 'Message', $headers);

if($success) {
    echo 'Email sent successfully';
} else {
    echo 'Failed to send email';
}
