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")) {
                                 $inheader = 0;
                          }
                          if ($inheader == 0) {
                                // echo $line;
                          }
          }
        if($line==1)
         {
       echo '短信发送成功 请查收 返回值'.$line ; 
         }else
         {
          echo '短信发送失败,请根据返回值查看相关错误问题 返回值'.$line ;
         }
fclose($fp);

?>
