PHPMailer::set │ public │ WP 1.0

Set or reset instance properties. You should avoid this function - it's more verbose, less efficient, more error-prone and harder to debug than setting properties directly. Usage Example: $mail->set('SMTPSecure', static::ENCRYPTION_STARTTLS); is the same as: $mail->SMTPSecure = static::ENCRYPTION_STARTTLS;.
