作曲家 在服务器上执行 PHP 邮件程序期间查找所需文件的错误消息

Question

我在尝试使用 PHP 邮件程序发送电子邮件时收到错误。我遵循了一个利用本地主机进行测试的教程，但是，我正在实时服务器上进行测试。我相信我的目录设置方式可能会导致问题。我使用 Composer 将 PHP Mailer 安装到目录中，并将整个目录上传到服务器上。以下是我遇到的错误：

[16-Jan-2018 08:36:33] PHP Warning:  require_once(__DIR__/composer/autoload_real.php)
[<a href='function.require-once'>function.require-once</a>]:
failed to open stream: No such file or directory in /public_html/netWorks/emailtests/vendor/autoload.php on line 5
[16-Jan-2018 08:36:33] PHP Fatal error:  require_once() [<a href='function.require'>function.require</a>]:
Failed opening required '__DIR__/composer/autoload_real.php' (include_path='.:/usr/lib64/php:/usr/share/pear') in
/public_html/netWorks/emailtests/vendor/autoload.php on line 5

这是索引.php -

<?php
require 'vendor/autoload.php';
$mail = new PHPMailer(true);                              // Passing `true` enables exceptions
try {
    //Server settings
    $mail->SMTPDebug = 2;                                 // Enable verbose debug output
    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'smtp.gmail.com';                       // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = '[e-mail]';                 // SMTP username
    $mail->Password = 'PW0RD';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 587;                                    // TCP port to connect to
    //Recipients
    $mail->setFrom('[e-mail]', 'Mailer');
    $mail->addAddress('[e-mail]', 'Kevin');     // Add a recipient
    $mail->addReplyTo('[e-mail]', 'Email Master Flex');
    //$mail->addCC('[e-mail]');
    //$mail->addBCC('[e-mail]');
    //Attachments
    //$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
    //$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
    //Content
    $mail->isHTML(true);                                  // Set email format to HTML
    $mail->Subject = 'You are receiving this because...';
    $mail->Body    = 'Stack Overflow is <b>AWESOME!</b>';
    $mail->AltBody = 'You are receiving this because Stack Overflow is AWESOME!';
    $mail->send();
    echo 'Message has been sent';
    } catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}

我尝试将自动加载的目录更改为/vendor/autoload.php但这也失败了。

我的

父文件夹有供应商文件夹，composer.json，composer.lock和我的index.php。供应商文件夹内是作曲家文件夹，phpmailer文件夹和autoload.php。有没有可能这是我遇到问题的地方？

我已经升级到PHP版本5.6 - 我现在收到此错误：

[16-Jan-2018 09:23:03 America/Denver] PHP Fatal error:  Class 'PHPMailer' not found in /public_html/netWorks/emailtests/index.php on line 4

Answer 1

感谢 Synchro 关于升级 PHP 的建议，我能够解决。我还需要添加命名空间：

use PHPMailerPHPMailerPHPMailer;
use PHPMailerPHPMailerException;
