How can PHP developers effectively debug issues with form submissions not functioning as expected, such as not receiving emails?

Issue: To debug form submission issues like not receiving emails, PHP developers can start by checking the email configuration settings in their PHP code, ensuring that the email server is properly set up and that the email headers are correctly formatted. They can also use debugging tools like error logs or print statements to track the flow of data and identify any potential errors in the email sending process. Code snippet: 

// Example PHP code to send an email using the mail function

$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email message.";
$headers = "From: sender@example.com";

// Send email
if (mail($to, $subject, $message, $headers)) {
    echo "Email sent successfully.";
} else {
    echo "Email sending failed.";
}
