How Can I Effectively Handle PHPMailer Errors Without Echoing Them to the Browser?

Error Handling with PHPMailer: Suppressing Echo'd Errors

In PHPMailer, error handling is managed through exceptions rather than solely through error messages echoed to the browser. To effectively handle errors, it's recommended to wrap your PHPMailer send call in a try-catch block.

require_once '../class.phpmailer.php';

$mail = new PHPMailer(true); // defaults to using php "mail()"; the true param enables exception handling

try {
  // Set email parameters
  $mail->AddReplyTo('[email protected]', 'First Last');
  $mail->AddAddress('[email protected]', 'John Doe');
  $mail->SetFrom('[email protected]', 'First Last');
  // ... configure the email further

  $mail->Send();
  echo "Message Sent OK\n";
} catch (phpmailerException $e) {
  echo $e->errorMessage(); // Pretty error messages from PHPMailer
} catch (Exception $e) {
  echo $e->getMessage(); // Generic error messages for other exceptions
}

In this example, exceptions thrown by PHPMailer (e.g., invalid recipient email address) will be caught and the error message displayed using errorMessage(). Other exceptions (e.g., connection issues) will be caught and the message displayed using getMessage().

Note that by catching exceptions, the script can offer better error handling capabilities, such as logging the error and returning a custom error message to the user.
