PHPMailer没有发送邮件

Question

Tring to send a confirmation mail after from saving data in the database. I have used PHPMailer.

My Code

<?php include_once 'config/init.php'; ?>
<?php
use PHPMailer\PHPMailer\PHPMailer;

$user = new user();

if(isset($_POST['submitsignup'])){

$date = array();

if($_POST['email']=='' || $_POST['password']=='' || $_POST['first_name']=='' || $_POST['last_name']==''){
    echo "Fill all the stuff";
}
else{ 
    $result=$user->checkemails($_POST['email']);
        if(!$result){
            $data["email"] = $_POST['email'];
            $data['password'] = $_POST['password'];
            $data['first_name'] =$_POST['first_name'];
            $data['last_name'] = $_POST['last_name'];

            $token = 'qwertyuiopasdfghjklzxcvbnm!$#()/1234567890';
            $token = str_shuffle($token);
            $token = substr($token,0,10);

            $user->signup($data,$token);

            include_once "PHPMailer/PHPMailer.php";

            $mail = new PHPMailer();
            $mail->setFrom("ahsan44411@gmail.com");
            $mail->addAddress($data["email"],$data["first_name"]);
            $mail->Subject = "Please verify name";
            $mail->isHTML(true);
            $mail->Body = "Please click on the Link below <br><br> 
            <a href='localhost/index.php'></a>";
            if($mail->send()){
                echo "Message sent";
            }else{
                echo "Something went wrong";
            }
        }
    else{
            echo "Email aleay present";
        }
    }   

}


$template = new Template('templates/signuptemp.php');

But I am getting errors like this

Warning: require_once(lib/PHPMailer\\PHPMailer\\Exception.php): failed to open stream: No such file or directory in C:\\wamp64\\www\\jobLister\\config\\init.php on line 10

Fatal error: require_once(): Failed opening required 'lib/PHPMailer\\PHPMailer\\Exception.php' (include_path='.;C:\\php\\pear') in C:\\wamp64\\www\\jobLister\\config\\init.php on line 10

My config\\init.php

<?php 


require_once 'config.php';

//Autoloader
function __autoload($class_name){
    require_once 'lib/'.$class_name.'.php';
}
?>

I can't really understand the problem, I would appreciate if you could explain the reason why this is happening.Cheers

Edit: Its not working because I am already using an autoloader to load my files and I should not be using include_once function in this case

I would recommend using Composer. But if you are not familiar with it, then just download the zip file and extract it in your website's directory. Create some test file like test.php or something and try this code.

<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require '<use correct path to PHPMailer here>/src/Exception.php';
require '<use correct path to PHPMailer here>/src/PHPMailer.php';

$body = "Hi! It works!";

$fromEmail = "<from address>"; //fill this
$password="<your secret password to gmail>"; //fill this
$toEmail = "<to address>"; //fill this

$mail = new PHPMailer(true);
try {
    //Server settings
    $mail->SMTPDebug = 2;
    $mail->isSMTP();    
    $mail->Host = 'smtp.gmail.com';  
    $mail->SMTPAuth = true;           
    $mail->Username = $fromEmail;        
    $mail->Password = $password;                
    $mail->SMTPSecure = 'tls';                      
    $mail->Port = 587;                           
    //Recipients
    $mail->setFrom($fromEmail, 'EMAIL FROM PHP TEST CODE');
    $mail->addAddress($toEmail);  

    //Content
    $mail->isHTML(true);                         
    $mail->Subject = 'TEST EMAIL';
    $mail->Body = $body;
    $mail->AltBody = 'IT WORKS!!!';
    $mail->send();
    echo 'mail sent!';
} catch (Exception $e) {
    echo $e;
}

Make sure you made the necessary setting in your gmail account to allow PHP to send mails. Without that, it won't work. If this code works, then build your program on top of this.
