近段时间接触短信平台机会比较多，想想好像客户方面的短信平台就是用PHP做出来的，心痒痒便找了一下资料学习一下，代码如下：

<?PHP  

$flag = 0; 
        //要post的数据 
$argv = array( 
                 'sn'=>'SDK-BBX-010-XXXXX', 
   'pwd'=>'XXXXXX', 
   'mobile'=>'134338XXXXX', //测试的手机号
                 'content'=>'你好吗,测试短信' 
   );    
//构造要post的字符串 
foreach ($argv as $key=>$value) { 
          if ($flag!=0) { 
                         $params .= "&"; 
                         $flag = 1; 
          } 
         $params.= $key."="; $params.= urlencode($value); 
         $flag = 1; 
          } 
         $length = strlen($params); 
                 //创建socket连接 
         $fp = fsockopen("sdk2.entinfo.cn",80,$errno,$errstr,10) or exit($errstr."--->".$errno); 
         //构造post请求的头 
         $header = "POST /z_send.aspx HTTP/1.1\r\n"; 
         $header .= "Host:sdk2.entinfo.cn\r\n"; 
         $header .= "Referer:/mobile/sendpost.php\r\n"; 
         $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; 
         $header .= "Content-Length: ".$length."\r\n"; 
         $header .= "Connection: Close\r\n\r\n"; 
         //添加post的字符串 
         $header .= $params."\r\n"; 
         //发送post的数据 
         fputs($fp,$header); 
         $inheader = 1; 
          while (!feof($fp)) { 
                         $line = fgets($fp,1024); //去除请求包的头只显示页面的返回数据 
                         if ($inheader && ($line == "\n" $line == "\r\n")) { 
              &
