php 简单实现邮件发送

初中目的是为了学习 WEBSOCKET ，所以写了一个简单发送邮件的例子，为后面打下基础。代码如下：

class Mail
{
   private $host;
   private $port;
     private $user;
     private $password;
   private $socket;

    public function __construct()
   {

//所使用邮件服务器
$this->host = 'smtp.outlook.com';

// 端口号这里是SSL加密方式，所以使用 465
$this->port = 465;

//邮件地址
$this->user = base64_encode('**********@163.com');

       //邮件密码
       $this->password = base64_encode('*******');

/**

* 连接服务器

**/
$this->socket = stream_socket_client("tcp://{$this->host}:{$this->port}",$errno,$errstr,30);

/**

* 将通讯管道设置为加密模式 SSL加密方式

         **/
       stream_socket_enable_crypto($this->socket, true, STREAM_CRYPTO_METHOD_SSLv23_CLIENT);
       // 获取服务器的状态码
       $response = fgets($this->socket);

        // 服务器返回状态码不是220 则连接失败
        if(strstr($response,'220') === false){
           echo "连接失败";
       }

   }

/**

* 执行服务器操作

    **/
   public function do_command($cmd,$return_code)
   {
       $result = fwrite($this->socket,$cmd);
       if(!$result){
           echo "发送 {$cmd} 失败.";
       }

        // 获取服务器的状态码
       $response = fgets($this->socket);
       print_r($response);
       if(strstr($response,"{$return_code}") === false){
           echo $response;
       }
   }

/**

* 组合命令发送邮件

* @param $from 来源邮箱地址

* @param $to 目标邮箱地址

* @param $subject 邮件主题

* @param $body 邮件内容

     **/
   public function send_mail($from,$to,$subject,$body)
   {
       $detail = "From:{$from} ";
       $detail .= "To:{$to} ";
       $detail .= "Subject:$subject ";
       $detail .= "Content-Type:text/plain; ";
       $detail .= "charset=gb2312 ";
       $detail .= $body;
       $this->do_command("HELO {$this->host} ",250);
       $this->do_command("AUTH LOGIN ",334);
       $this->do_command("{$this->user} ",334);
       $this->do_command("{$this->password} ",235);
       $this->do_command("MAIL FROM: <{$from}> ",250);
       $this->do_command("RCPT TO: <{$to}> ",250);
       $this->do_command("DATA ",354);
       $this->do_command($detail." . ",250);
       $this->do_command("QUIT ",221);
   }

/**

* 关闭通讯管道设置为加密模式，套接子

     **/
   public function close()
   {
       stream_socket_enable_crypto($this->socket, false);

       fclose($this->socket);
   }
}

测试

$mail = new Mail();
$body = "hello world";
$mail->send_mail("********@163.com","********@qq.com","testsubject",$body);
$mail->close();

还有邮箱地址的验证功能，这里没实现，因为只是为了如何实现SOCKET通信。
