    // These must be at the top of your script,not inside a function
    use PHPMailer\PHPMailer\PHPMailer;
    use PHPMailer\PHPMailer\SMTP;
    use PHPMailer\PHPMailer\Exception;
    
    
    //require 'vendor/autoload.php';
    
     include("PHPMailer.php"); 
     include("SMTP.php"); 
     include("Exception.php"); 
    
    $mail = new PHPMailer(true);
    
    try {
        //Server settings
        $mail->SMTPDebug = SMTP::DEBUG_SERVER;                      // Enable verbose debug output
        $mail->isSMTP();                                            // Send using SMTP
        $mail->Host       = 'ssl://smtp.gmail.com';                    // Set the SMTP server to send through
        $mail->SMTPAuth   = true;                                   // Enable SMTP authentication

        $mail->Password   = 'xxxxx';                               // SMTP password
        $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;         // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
        $mail->Port       = 465;                                    // TCP port to connect to,use 465 for `PHPMailer::ENCRYPTION_SMTPS` above
    
        //Recipients
        $mail->setFrom('[e-mail]','Mailer');
