php - Pear Mail "Unable to find class for driver smtp"找不到文件，就在那里

Question

我的 VPS 运行的是 CentOS 5.3。我已经安装了 pear、Mail 和 Net_Mail。当我尝试发送邮件时，我得到“无法找到驱动程序 smtp 的类”。我查看了 Mail.php，发现我的 pear 目录中需要一个“Mail/smtp.php”，它是存在的。我验证了 php 包含目录，并通过 chown 将所有权限重置为 apache。我查了一下chmod，都是644。

我的代码:

    $from = "Admin <admin@myemail.com>";
$to = "New User <".$email.">";
$subject = "Welcome to MyEmail!";
$body = "Thanks for choosing <MyEmail>! We strive to provide 24/7 email service and support. If you have ANY issues, concerns, etc, please reply to this email, or simply compose a new one to: myemail@email.com !";
$host = "localhost";
$username = "username";
$password = "password"; 
$headers = array ('From' => $from,
    'To' => $to,
    'Subject' => $subject);
$smtp = Mail::factory('smtp',
    array ('host' => $host,
    'auth' => true,
    'username' => $username,
    'password' => $password));
if (PEAR::isError($smtp)) {
    echo("<p>" . $smtp->getMessage() . "</p>");
}
$mail = $smtp->send($to, $headers, $body);
if (PEAR::isError($mail)) {
    echo("<p>" . $mail->getMessage() . "</p>");
} else {
    echo("<p>Message successfully sent!</p>");
}

Answer 1

当在开头添加 require_once 'Mail.php'; 时，您提供的代码在这里有效。

Mail/smtp.php 文件在您的服务器上是什么 md5 散列？它是否包含 class Mail_smtp 行？
