php - fatal error : Class 'PHPMailer' not found in

Question

Fatal error: Class 'PHPMailer' not found in C:\wamp\www\sendemail.php on line 13

这是第 13 行:

$mail = new PHPMailer();

我已经研究过了，他们说你需要这些:

require_once('class.pop3.php');
require_once('class.phpmailer.php');
require_once('class.smtp.php');
require_once('PHPMailerAutoload.php');

但我已经有了这些，它们与 sendemail.php 位于同一文件夹中，但仍然存在相同的错误。

<?php
/**
 * This example shows settings to use when sending via Google's Gmail servers.
*/
//SMTP needs accurate times, and the PHP time zone MUST be set
//This should be done in your php.ini, but this is how to do it if you don't have access to that
date_default_timezone_set('Etc/UTC');
require_once('class.pop3.php');
require_once('class.phpmailer.php');
require_once('class.smtp.php');
require_once('PHPMailerAutoload.php');
//Create a new PHPMailer instance
$mail = new PHPMailer;
//Tell PHPMailer to use SMTP
$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 = 'smtp.gmail.com';
// use
// $mail->Host = gethostbyname('smtp.gmail.com');
// if your network does not support SMTP over IPv6
//Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission
$mail->Port = 587;
//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 = "email@email.com";
//Password to use for SMTP authentication
$mail->Password = "password";
//Set who the message is to be sent from
$mail->setFrom('email@email.com', 'name');
//Set an alternative reply-to address
//$mail->addReplyTo('replyto@example.com', 'First Last');
//Set who the message is to be sent to
$mail->addAddress('email@sample.com', 'name');
//Set the subject line
$mail->Subject = 'PHPMailer GMail SMTP test';
//Read an HTML message body from an external file, convert referenced images to embedded,
//convert HTML into a basic plain-text alternative body
$mail->msgHTML(file_get_contents('contents.html'), dirname(__FILE__));
//Replace the plain text body with one created manually
$mail->AltBody = 'This is a plain-text message body';
//Attach an image file
//$mail->addAttachment('images/phpmailer_mini.png');
//send the message, check for errors
if (!$mail->send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message sent!";
}

这是我的文件布局:

我遇到了同样的问题，并设法通过在用于发送邮件的 PHP 脚本的最顶部输入以下两行来解决它 - 而不仅仅是在我需要d 的文件中。

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

如果它也适用于您，请告诉我。
