致命错误：Class＆＃39; Mail＆＃39;在mailtest.php中找不到

Question

当我尝试使用php发送邮件时，我收到此错误：

Fatal error: Class 'Mail' not found in C:\Program Files (x86)
\Apache Software Foundation\Apache2.2\htdocs\pn\mailtest.php
on line 10

这是我的PHP代码：

<?php
  $from="sjoseph@seisystems.com";
  $to="dianahelene@gmail.com";
  $subject="testmail";
  $host="Sei-mail01";

  $headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject);

  $smtp = Mail::factory('smtp', array ('host' => $host, 'auth' => false));
  $mail = $smtp->send($to, $headers, $message);
?>

为什么

Answer 1

您需要在require_once标记后加载<?php的Mail类：

require_once 'Mail.php';
