"use PHPMailer\PHPMailer\PHPMailer" not working

I am trying to make a form that can contact me via email with PHP. I am new to PHP so after watching a couple of videos I am making with PHPMailer. After I downloaded the zip file from GitHub and installing composer and these things, the code shows some errors. When I declare "use\PHPMailer\PHPMailer\PHPMailer," it says Unexpected, 'Unknown'.

My code is this

<?PHP
//Import PHPMailer classes into the global namespace
//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;

//Load Composer's autoloader
require 'vendor/autoload.php';

//Instantiation and passing `true` enables exceptions
$mail = new PHPMailer(true);

try {
//Server settings
$mail->SMTPDebug = SMTP::DEBUG_SERVER;                      //Enable verbose debug output
$mail->isSMTP();                                            //Send using SMTP
$mail->Host       = 'smtp.example.com';                     //Set the SMTP server to send through
$mail->SMTPAuth   = true;                                   //Enable SMTP authentication
$mail->Username   = 'user@example.com';                     //SMTP username
$mail->Password   = 'secret';                               //SMTP password
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;         //Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` encouraged
$mail->Port       = 587;                                    //TCP port to connect to, use 465 for `PHPMailer::ENCRYPTION_SMTPS` above

//Recipients
$mail->setFrom('from@example.com', 'Mailer');
$mail->addAddress('joe@example.net', 'Joe User');     //Add a recipient
$mail->addAddress('ellen@example.com');               //Name is optional
$mail->addReplyTo('info@example.com', 'Information');
$mail->addCC('cc@example.com');
$mail->addBCC('bcc@example.com');

//Attachments
$mail->addAttachment('/var/tmp/file.tar.gz');         //Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    //Optional name

//Content
$mail->isHTML(true);                                  //Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

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

The code is from the GitHub page I just copied and pasted it to test it. I edited the JSON file and all of them but it doesn't work. Appreciate the help from everyone. Thank you

The most likely explanation is that you are running PHP that’s older than version 5.3, which is when namespaces and the use statement were introduced. Upgrade your PHP - any new development should be using 8.0.

Move your autoload to the top of the file, using PSR4 before the autoload is in wont work.

<?php
require 'vendor/autoload.php';
//Import PHPMailer classes into the global namespace
//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;
...

Though you should really keep your autoloader in a seperate file. e.g. a index.php and create a Mailer class of your own.

How you would go about doing this would be adding an autoload to your composer.json

{
    "name": "acme/app",
    "type": "project",
    "authors": [
        {
            "name": "some name",
            "email": "email@example.com"
        }
    ],
    "require": {
        "phpmailer/phpmailer": "^6.4"
    },
    "autoload": {
        "psr-4": {"Acme\\": "src/"}
    }
}

Creating a src folder with a file named App.php

<?php
namespace Acme;

class App
{
    public static function boot()
    {
        echo 'works'; // Do what ever you want. 
    }
}

Create a index.php in the root

<?php
require 'vendor/autoload.php';

Acme\App::boot();

then run composer install or composer du and run php index.php and your set.

I have seen cases where the classes were placed inside a PHP function. That will throw an error.

From the documentation:

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;
