php 致命错误：找不到“PHPMailer”类

Fatal error: Class 'PHPMailer' not found

提问by iori

• I tried :include_once('C:\Inetpub\wwwroot\php\PHPMailer\PHPMailerAutoload.php');

• 我试过 ：include_once('C:\Inetpub\wwwroot\php\PHPMailer\PHPMailerAutoload.php');

Fatal error: Class 'PHPMailer' not found in C:\Inetpub\wwwroot\php\index.php on line 151

致命错误：在第 151 行的 C:\Inetpub\wwwroot\php\index.php 中找不到“PHPMailer”类

I place the PHPMailerAutoload.phpin the same directory as my script.

我将它PHPMailerAutoload.php放在与我的脚本相同的目录中。

Can someone help me with this ?

有人可以帮我弄这个吗 ？

all answers are outdated now. Most current version (as of Feb 2018) does not have autoload anymore, and PHPMailer should be initialized as follows:

现在所有的答案都过时了。大多数当前版本（截至 2018 年 2 月）不再具有自动加载功能，PHPMailer 应初始化如下：

<?php

  require("/home/site/libs/PHPMailer-master/src/PHPMailer.php");
  require("/home/site/libs/PHPMailer-master/src/SMTP.php");

    $mail = new PHPMailer\PHPMailer\PHPMailer();
    $mail->IsSMTP(); // enable SMTP

    $mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true; // authentication enabled
    $mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail
    $mail->Host = "smtp.gmail.com";
    $mail->Port = 465; // or 587
    $mail->IsHTML(true);
    $mail->Username = "xxxxxx";
    $mail->Password = "xxxx";
    $mail->SetFrom("[email protected]");
    $mail->Subject = "Test";
    $mail->Body = "hello";
    $mail->AddAddress("[email protected]");

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

Doesn't sound like all the files needed to use that class are present. I would start over:

听起来不像使用该类所需的所有文件都存在。我会重新开始：

1. Download the package from https://github.com/PHPMailer/PHPMailerby clicking on the "Download ZIP" button on the far lower right of the page.
2. extract the zip file
3. upload the language folder, class.phpmailer.php, class.pop3.php, class.smtp.php, and PHPMailerAutoload.php all into the same directory on your server, I like to create a directory on the server called phpmailer to place all of these into.
4. Include the class in your PHP project: require_once('phpmailer/PHPMailerAutoload.php');

1. 单击页面最右下方的“下载 ZIP”按钮，从https://github.com/PHPMailer/PHPMailer下载包。
2. 解压压缩文件
3. 将语言文件夹class.phpmailer.php、class.pop3.php、class.smtp.php和PHPMailerAutoload.php都上传到你服务器上的同一个目录中，我喜欢在服务器上创建一个名为phpmailer的目录来放置所有这些成。
4. 在您的 PHP 项目中包含该类： require_once('phpmailer/PHPMailerAutoload.php');

This answers in an extension to what avs099 has given above, for those who are still having problems:

对于那些仍然有问题的人，这是对 avs099 上面给出的内容的扩展：

1.Makesure that you have php_openssl.dll installed(else find it online and install it);

1.确保你已经安装了php_openssl.dll（否则网上找来安装）；

2.Go to your php.ini; find extension=php_openssl.dll enable it/uncomment

2.转到你的php.ini；找到 extension=php_openssl.dll 启用它/取消注释

3.Go to githuband downland the latetest version :6.0 at this time.

3.此时去github下载最新版本：6.0。

4.Extract the master copy into the path that works better for you(I recommend the same directory as the calling file)

4.将主副本解压到更适合您的路径中（我推荐与调用文件相同的目录）

Now copy this code into your foo-mailer.php and render it with your gmail stmp authentications.

现在将此代码复制到您的foo-mailer.php 并使用您的 gmail stmp 身份验证呈现它。

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


    $mail = new PHPMailer\PHPMailer\PHPMailer();
    $mail->IsSMTP(); 

    $mail->CharSet="UTF-8";
    $mail->Host = "smtp.gmail.com";
    $mail->SMTPDebug = 1; 
    $mail->Port = 465 ; //465 or 587

     $mail->SMTPSecure = 'ssl';  
    $mail->SMTPAuth = true; 
    $mail->IsHTML(true);

    //Authentication
    $mail->Username = "[email protected]";
    $mail->Password = "*******";

    //Set Params
    $mail->SetFrom("[email protected]");
    $mail->AddAddress("[email protected]");
    $mail->Subject = "Test";
    $mail->Body = "hello";


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

Disclaimer:The original owner of the code above is avs099 with just my little input.

免责声明：以上代码的原始所有者是 avs099，只是我的一点点投入。

Take note of the additional:

注意额外的：

a) (PHPMailer\PHPMailer) namespace:needed for name conflict resolution.

a) (PHPMailer\PHPMailer) 命名空间：需要解决名称冲突。

b) The (require("/PHPMailer-master/src/Exception.php");):It was missing in avs099's code thus the problem encountered by aProgger,you need that line to tell the mailer class where the Exception class is located.

b) (require("/PHPMailer-master/src/Exception.php");): 它在avs099的代码中丢失，因此aProgger遇到的问题，您需要该行告诉邮件程序类Exception类所在的位置.

This is just namespacing. Look at the examples for reference - you need to either use the namespaced class or reference it absolutely, for example:

这只是命名空间。查看示例以供参考 - 您需要使用命名空间类或绝对引用它，例如：

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

//Load composer's autoloader
require 'vendor/autoload.php';

回答by fyrye

I suggest you look into getting composer. https://getcomposer.orgComposer makes getting third-party libraries a LOT easier and using a single autoloader for all of them. It also standardizes on where all your dependencies are located, along with some automatization capabilities.

我建议你考虑获取composer. https://getcomposer.orgComposer 使获取第三方库变得更加容易，并且所有这些库都使用一个自动加载器。它还标准化了所有依赖项的位置，以及一些自动化功能。

Download https://getcomposer.org/composer.pharto C:\Inetpub\wwwroot\php

下载https://getcomposer.org/composer.phar到C:\Inetpub\wwwroot\php

Delete your C:\Inetpub\wwwroot\php\PHPMailer\directory.

删除您的C:\Inetpub\wwwroot\php\PHPMailer\目录。

Use composer.pharto get the phpmailer package using the command line to execute

使用composer.phar命令行获取phpmailer包执行

cd C:\Inetpub\wwwroot\php
php composer.phar require phpmailer/phpmailer

After it is finished it will create a C:\Inetpub\wwwroot\php\vendordirectory along with all of the phpmailer files and generate an autoloader.

完成后，它将创建一个C:\Inetpub\wwwroot\php\vendor包含所有 phpmailer 文件的目录并生成一个自动加载器。

Next in your main project configuration file you need to include the autoload file.

接下来在您的主项目配置文件中，您需要包含自动加载文件。

require_once 'C:\Inetpub\wwwroot\php\vendor\autoload.php';

require_once 'C:\Inetpub\wwwroot\php\vendor\autoload.php';

The vendor\autoload.phpwill include the information for you to use $mail = new \PHPMailer;

在vendor\autoload.php将包括信息供您使用$mail = new \PHPMailer;

Additional information on the PHPMailer package can be found at https://packagist.org/packages/phpmailer/phpmailer

I had a number of errors similar to this. Make sure your setFrom email address is valid in $mail->setFrom()

我有许多与此类似的错误。确保您的 setFrom 电子邮件地址在$mail->setFrom()

I was with the same problem except with a slight difference, the version of PHPMailer 6.0, by the good friend avs099 I know that the new version of PHPMailer since February 2018 does not support the autoload, and had a serious problem to instantiate the libraries with the namespace in MVC, I leave the code for those who need it.

我遇到了同样的问题，除了略有不同之外，PHPMailer 6.0 的版本，由好朋友 avs099 我知道自 2018 年 2 月以来的新版本 PHPMailer 不支持自动加载，并且在实例化库时遇到了严重的问题MVC 中的命名空间，我将代码留给需要它的人。

I resolved error copying the files class.phpmailer.php , class.smtp.php to the folder where the file is PHPMailerAutoload.php, of course there should be the file that we will use to send the email.

我解决了将文件 class.phpmailer.php , class.smtp.php 复制到文件为 PHPMailerAutoload.php 的文件夹中的错误，当然应该有我们将用来发送电子邮件的文件。

Just download composer and install phpMailler autoloader.php

https://github.com/PHPMailer/PHPMailer/blob/master/composer.json

once composer is loaded use below code:

    require_once("phpMailer/class.phpmailer.php");
    require_once("phpMailer/PHPMailerAutoload.php");

    $mail = new PHPMailer(true); 
            $mail->SMTPDebug = true;
            $mail->SMTPSecure = "tls";
            $mail->SMTPAuth   = true;
            $mail->Username   = 'youremail id';
            $mail->Password   = 'youremail password';
            $mail_from        = "youremail id";
            $subject          = "Your Subject";
            $body             = "email body";
            $mail_to          = "receiver_email";
            $mail->IsSMTP(); 
            try {
                  $mail->Host= "smtp.your.com";
                  $mail->Port = "Your SMTP Port No";// ssl port :465, 
                  $mail->Debugoutput = 'html';
                  $mail->AddAddress($mail_to, "receiver_name");
                  $mail->SetFrom($mail_from,'AmpleChat Team'); 
                  $mail->Subject = $subject;
                  $mail->MsgHTML($body);
                  $mail->Send();
                 $emailreturn = 200;
                } catch (phpmailerException $e) {
                  $emailreturn = $e->errorMessage();             
                } catch (Exception $e) {
                 $emailreturn = $e->getMessage();
                }
    echo $emailreturn;

Hope this will work.

希望这会奏效。

Just from reading what you have written, you will need to add the file class.phpmailer.php to your directory as well.

仅通过阅读您所写的内容，您还需要将文件 class.phpmailer.php 添加到您的目录中。
