PHPMailer - PHP Error

PHP Fatal error:  Class 'Mail' not found in /.............../crons/Mail.php on line 2

知道为什么代码中没有提到它时它说"邮件"吗？这是我的PHP脚本：

<?php
    require("database.php");
    include_once("Mail.php");
    $query = $db->query("SELECT * FROM `emails` WHERE `sent`='0' LIMIT 50");
    if ($query->rowCount()>=1)
    {
        while($row = $query->fetch(PDO::FETCH_ASSOC))
        {
        $email = stripslashes($row['message']);
        //Create a new PHPMailer instance
        $mail = new PHPMailer();
        $mail->isSMTP();
        //Enable SMTP debugging
        // 0 = off (for production use)
        // 1 = client messages
        // 2 = client and server messages
        $mail->SMTPDebug = 2;
        //Ask for HTML-friendly debug output
        $mail->Debugoutput = 'html';
        //Set the hostname of the mail server
        $mail->Host = 'localhost';
        //Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission
        $mail->Port = 25;
        //Set the encryption system to use - ssl (deprecated) or tls
        $mail->SMTPSecure = 'tls';
        //Whether to use SMTP authentication
        $mail->SMTPAuth = true;
        //Username to use for SMTP authentication - use full email address for gmail
        $mail->Username = "help@pingrglobe.com";
        //Password to use for SMTP authentication
        $mail->Password = "ping123rglobe";
        //Set who the message is to be sent from
        $mail->setFrom('help@pingrglobe.com', 'PingrGlobe Support');
        //Set an alternative reply-to address
        $mail->addReplyTo('help@pingrglobe.com', 'PingrGlobe Support');
        //Set who the message is to be sent to
        $mail->addAddress($row['email'], 'John Doe');
        //Set the subject line
        $mail->Subject = $row['subject'];
        //Replace the plain text body with one created manually
        $mail->Body = $email;
        //send down here etc

我得到了上面代码所述的错误，它没有做任何事情。全新的PHPMailer下载，"邮件"甚至不是一个正在使用的类，我很困惑。

您可能需要邮件的前几行.php：
