在 phpmailer 中找不到类 SMTP

Question

我的 php 邮件功能遇到了这个问题。我尝试更改所需的文件，但仍然相同。谁能帮我解决这个错误。

这是我的 phpmailer 代码：

$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'ssl'; 
$mail->Host = "smtp.gmail.com";
$mail->Port = 587;
$mail->IsHTML(true);
$mail->Username = "testnoreply@gmail.com";
$mail->Password = "test";
$mail->SetFrom("testnoreply@gmail.com");
$mail->Subject = "Membership expire notice";
$mail->Body = "Dear ICONIS member your membership is going to expire please renew it";
$mail->AddAddress($em);

if (!$mail->Send()) {
  echo "Mailer Error: " .$mail->ErrorInfo;
} else {
  echo "Mail has been sent";
}

Answer 1

您确定您的文件夹中同时拥有 class.phpmailer.php 和 class.smtp.php 吗？

在包含class.phpmailer.php之前尝试包含class.smtp.php，如下：

<?php
include 'class.smtp.php';
include 'class.phpmailer.php';
// your code goes here

然后告诉你是否有错误。

只需下载所有文件，将文件解压缩到一个文件夹中并从该文件夹中包含 PHPMailerAutoload.php。

<?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 'YOURFOLDERNAME/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 = "username@gmail.com";
//Password to use for SMTP authentication
$mail->Password = "yourpassword";
//Set who the message is to be sent from
$mail->setFrom('from@example.com', 'First Last');
//Set an alternative reply-to address
$mail->addReplyTo('replyto@example.com', 'First Last');
//Set who the message is to be sent to
$mail->addAddress('whoto@example.com', 'John Doe');
//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!";
}

试试

require 'PHPMailerAutoload.php';
$mail = new PHPMailer;

而不是

require 'class.phpmailer.class.php';
$mail = new PHPMailer;
