How can PHP developers troubleshoot and debug email sending issues in their scripts?

To troubleshoot and debug email sending issues in PHP scripts, developers can start by checking the email configuration settings, ensuring that the SMTP server details are correct, and verifying that the email function is properly called. Additionally, developers can enable error reporting to catch any potential errors during the email sending process.

// Example code snippet to troubleshoot email sending issues

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

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