尝试与 PHP 建立 SMTP 连接时出现错误？

Question

您可以在下面看到我的 send_mail.php 文件。

    <?php
  require("PHPMailer/src/Exception.php");
  require("PHPMailer/src/PHPMailer.php");
  require("PHPMailer/src/SMTP.php");

  use PHPMailer\PHPMailer\Exception;
  use PHPMailer\PHPMailer\PHPMailer;
  use PHPMailer\PHPMailer\SMTP;
  /*
  require_once("mail/PHPMailerAutoload.php");
  */
  session_start();
  $sifre = $_SESSION["sifre"];
  /*
  echo $sifre . "<br>";
  */
  $mail = new PHPMailer();
  $mail->IsSMTP();
  $mail->SMTPDebug = 2; 
  $mail->SMTPAuth = true;
  $mail->SMTPSecure = 'tls';
  $mail->Host = 'smtp.yandex.com';
  $mail->Port = 587;
  $mail->IsHTML(true);
  $mail->SetLanguage("tr", "phpmailer/language");
  $mail->CharSet ="utf-8";
  $mail->Username = "hakantalha1@yandex.com"; 
  $mail->Password = "h123456";
  $mail->SetFrom("info@mydomain.com", "Değer Kaybı"); // Mail attigimizda yazacak isim
  $mail->AddAddress("hakantalha1@yandex.com"); // Maili gonderecegimiz kisi/ alici
  $mail->Subject = "Şifremi Unuttum"; // Konu basligi
  $mail->Body = "Şifreniz: " . $sifre; // Mailin icerigi
  if(!$mail->Send()){
    echo "Mailer Error: ".$mail->ErrorInfo;
} else {
    echo "Mesaj gonderildi";
}
?>

您可以在下方看到我收到的错误。

我正在尝试与 XAMPP 建立连接。我有 PHPMailer 5.5 版并编辑了 XAMPP .ini 文件。你能帮我吗，我收到错误的原因是什么？
