Are there any best practices for troubleshooting PHP mailer issues?

Issue: If PHP mailer is not sending emails, it could be due to misconfigured settings or server restrictions. To troubleshoot this issue, ensure that the email server settings are correct, check for any firewall or security restrictions blocking outgoing emails, and verify that the PHP mailer library is properly installed and up to date. 

// Example PHP code snippet to troubleshoot PHP mailer issues

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php'; // Path to PHP mailer autoload file

$mail = new PHPMailer(true);

try {
    // Server settings
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your@example.com';
    $mail->Password = 'your_password';
    $mail->SMTPSecure = 'ssl';
    $mail->Port = 465;

    // Recipient
    $mail->setFrom('your@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    // Content
    $mail->isHTML(true);
    $mail->Subject = 'Subject';
    $mail->Body = 'Email content';

    $mail->send();
    echo 'Email sent successfully';
} catch (Exception $e) {
    echo "Email could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
