How can PHP developers effectively use log files in XAMPP for debugging mail sending issues?

To effectively debug mail sending issues in XAMPP, PHP developers can utilize log files to track the process and identify any errors or failures. By enabling logging in the PHP configuration and specifying a log file path, developers can easily monitor the mail sending process and troubleshoot any issues that may arise.

// Enable error logging for PHP
ini_set('log_errors', 1);
ini_set('error_log', 'path/to/log/file.log');

// Code for sending email
$to = 'recipient@example.com';
$subject = 'Test Email';
$message = 'This is a test email.';
$headers = 'From: sender@example.com';

if (mail($to, $subject, $message, $headers)) {
    echo 'Email sent successfully.';
} else {
    echo 'Failed to send email. Check log file for details.';
}
