php通過socket編程，以SMTP將郵件發送到指定的QQ郵箱裡面。____編程

在剛開始先配置好php.ini檔案：

（1）我是在window 7 下面進行配置的。

（2）將擴充extension=php_openssl.dll，extension=php_sockets.dll開啟

（3）設定allow_url_fopen = On，SMTP = localhost，smtp_port = 25，

          當然sendmail_from，sendmail_path可以不用設定。但在Unix下sendmail_path需要設定

接下來用qq郵箱測試時需要設定：

（1）開啟qq郵箱設定。

（2）然後在賬戶中將pop3/smtp勾選，儲存設定。當然這裡注意自己的郵箱和測試郵箱都要開啟。

這裡簡單介紹一下HTTP狀態含義一邊測試使用,這是我測試瀏覽器顯示的內容：

     220 smtp.qq.com Esmtp QQ Mail Server 
   250-smtp.qq.com 
   250-PIPELINING 
   250-SIZE 52428800 
   250-STARTTLS 
   250-AUTH LOGIN PLAIN 
   250-AUTH=LOGIN SMTP使用者驗證
   250-MAILCOMPRESS 
   250 8BITMIME 
   334 VXNlcm5hbWU6 輸入使用BASE64編碼的使用者名稱
   334 UGFzc3dvcmQ6 輸入使用BASE64編碼的密碼
   235 Authentication successful 驗證通過
   250 Ok 接受者郵件地址

   250 Ok 告訴伺服器我要開始發送郵件資料了
   354 End data with . 
     250 Ok: queued as 
    郵件發送成功

下面便是發送郵件的一個SMTP類，經過本人修改，沒問題了，class.mail.php：
