PHPMailer Undefined type 'PHPMailer\PHPMailer\PHPMailer'-CodePudding

When i try to type new PHPMailer(true); Then its keep giving me the same error:

Undefined type 'PHPMailer\PHPMailer\PHPMailer'.

Can you tell whats the problem? Thanks!

Code:

<?php
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];

require "vendor/autoload.php";

use PHPMailer\PHPMailer\PHPMailer;

$mail = new PHPMailer(true);

$mail->isSMTP();
$mail->SMTPAuth = true;

$mail->Host = "smtp.rackhost.hu";
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->SMTPAuth = true;
$mail->Port = 465;

$mail->Username = "[email protected]";
$mail->Password = "Teszt123";

$mail->setFrom("[email protected]", "Djalms");
$mail->addAddress("[email protected]");

$mail->Subject = $subject;
$mail->Body = $message;

$mail->send();

echo "email sent";
?>

The username, Password and the setFrom is empty to keep privacy.

CodePudding user response：

If you've now managed to install PHPMailer with composer (which would explain why you were getting the class not found error), I expect the 504 is caused by this combination of settings:

$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port = 465;

That's asking it to do explicit TLS on a port expecting implicit TLS, which will not work, but might take a long time to fail, leading to the 504 error. The difference is explained in the docs, but either of these two combinations should work:

$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port = 587;

$mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS;
$mail->Port = 465;
