I am getting error like:

My code:

我的代码:

require_once 'Mail.php';

$from = "me@example.com>";

$to = "you@gmail.com>";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";

$host = "mail.example.com";

$username = "me";
$password = "test";

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

$smtp = Mail::factory('smtp',
  array ('host' => $host,
    'auth' => true,
    'username' => $username,
    'password' => $password));
$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
  echo("<p>" . $mail->getMessage() . "</p>");
 } else {
  echo("<p>Message successfully sent!</p>");
 }

3 个解决方案

#1

if you have ssh access, you can login and run

如果您有ssh访问，您可以登录并运行

which pear

if it's installed it will print something like this

如果安装了，它会打印出这样的东西

/usr/bin/pear

#2

Use this code

使用这个代码

require_once 'System.php';
var_dump(class_exists('System'));

When this is true, pear is installed. More info: http://pear.php.net/manual/en/installation.checking.php

当这是真的时，就安装了pear。更多信息:http://pear.php.net/manual/en/installation.checking.php。

#3

The following code might help if the server is on ubuntu.

如果服务器在ubuntu上，下面的代码可能会有所帮助。

sudo apt-get install php-pear

sudo pear install mail

sudo pear install Net_SMTP

sudo pear install Auth_SASL

sudo pear install mail_mime
