PHPMAILER错误：发生了某些错误

Question

我遇到了错误：发生了一些错误

当我单击刷新到in.php页面以测试发送电子邮件时-> 在浏览器中出现“发生了某些错误”，我不知道问题出在哪里

我需要帮助！

   <?php 
         //include phpmailer.php

      require("PHPMailer-master/src/PHPMailer.php");
      require("PHPMailer-master/src/SMTP.php");
      require("PHPMailer-master/src/Exception.php");


    //create an instance of PHPMailer
    $mail = new PHPMailer\PHPMailer\PHPMailer;

      //set a host
     $mail->Host = "smtp.gmail.com";

       //set authentication to true
       $mail->SMTPAuth = true;

      //set login details for Gmail account
      $mail->Username = "xxxxxx@gmail.com";
      $mail->Password = "xxxxxxxxxx";

     //set type of protection
      $mail->SMTPSecure = "ssl"; //or we ca use TLS

     //set a port
    $mail->Port  =465; //or 587 if TLS

   //set subject
      $mail->Subject = "Test email";

   //set body
    $mail->Body = "This is our body...";

   //set who is sending an email
   $mail->setFrom("xxxxxx@gmail.com","xxxxx");

    //set where we are sending email
      $mail->addAddress("xxxxxx@yahoo.com");

   //send an email
   if($mail->send()){

     echo "mail is sent";
   }
  else {
        echo "something wrong happened";
   }
