SMTP connect()失败PHPmailer – PHP

我是PHP的新手.我试图通过PHPmailer向自己发送一封示例电子邮件.我正在使用gmail的smtp服务器.我试图从我的Gmail帐户发送一个示例邮件到我的雅虎帐户.但我收到错误：邮件程序错误：SMTP连接()失败.
这是代码：

<?PHP

require "class.PHPmailer.PHP";
$mail = new PHPMailer(); 
$mail->IsSMTP();                              // send via SMTP
$mail->Host = "ssl://smtp.gmail.com";
$mail->SMTPAuth = true;                       // turn on SMTP authentication
$mail->Username = "[e-mail]";        // SMTP username
$mail->Password = "mypassword";               // SMTP password
$webmaster_email = "[e-mail]";       //Reply to this email ID
$email="[e-mail]";                // Recipients email ID
$name="My Name";                              // Recipient's name
$mail->From = $webmaster_email;
$mail->Port = 465;
$mail->FromName = "My Name";
$mail->AddAddress($email,$name);
$mail->AddReplyTo($webmaster_email,"My Name");
$mail->WordWrap = 50;                         // set word wrap
$mail->IsHTML(true);                          // send as HTML
$mail->Subject = "subject";
$mail->Body = "Hi,
This is the HTML BODY ";                      //HTML Body 
$mail->AltBody = "This is the body when user views in plain text format"; //Text Body 

if(!$mail->Send())
{
echo "Mailer Error: " . $mail->ErrorInfo;
}
else
{
echo "Message has been sent";
}
?>

我在Windows 7 64位计算机上使用WAMP服务器.可能是什么问题？
请帮我解决这个问题.谢谢！

解决方法:

您需要添加Host参数

$mail->Host = "ssl://smtp.gmail.com"; 

另外,检查您是否启用了open_ssl.

<?PHP
echo !extension_loaded('openssl')?"Not Available":"Available";
