经过一场战斗，获得梨的正确位置后，我的代码不会产生任何错误。但是它不会发送电子邮件。电子邮件正文是从一个表单生成的，该表单首先将数据输入 mysql 数据库，然后将相同的数据通过电子邮件发送给一个人，然后该人将这些数据用于任何用途。我已经在这个论坛和其他（这是最好的）上阅读了大量的问题和答案，并且我编写的大部分代码都受到了这个论坛的启发。gmail账号有效，密码正确。任何帮助或建议将不胜感激。
pear 和 pear mail 安装在服务器上并且似乎正在工作（至少没有产生任何错误）这是我的代码：
//Email process code
ini_set('display_errors','on');
error_reporting(E_ALL);
/*
require_once 'System.php';
if(class_exists('System')===true) {
echo 'PEAR is installed!';
} else {
echo 'PEAR is not installed :(';
}
*/
set_include_path('/home/surfcup/php/');
require_once "Mail.php";
$from = "<me@gmail.com>";
$ToEmail = "<new@apdapalabs.com>";
$EmailSubject = 'Hotel Registration Form';
$host ="ssl://smtp.gmail.com";
$port ="465";
$username = "myAccount@gmail.com";
$password = "password";
$headers = array ('From' => $from, 'To'=> $ToEmail, 'Subject'=> $EmailSubject);
$smtp = Mail::factory('smtp',
array ('host'=> $host,
'port'=> $port,
'auth'=> true,
'username'=> $username,
'password'=> $password));
$MESSAGE_BODY = "Event: ".$Event."\n";

$MESSAGE_BODY .= "Check Out Date: ".$Check_Out."\n";

$mail = $smtp->send($ToEmail, $headers, $MESSAGE_BODY);
if (PEAR::isError($mail)){
echo("<p>" . $mail->getMessage . "</p>");
echo("\n");
echo("<p>" . $mail->getDebugInfo . "</p>");
