用PHP模拟Post来提交数据

<？PHP    
     $flag = 0;
    //要post的数据
$argv = array(
     'var1'=>'abc',
     'var2'=>'你好吗');
//构造要post的字符串
foreach ($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
     $fp = fsockopen("127.0.0.1",80,$errno,$errstr,10) or exit($errstr."--->".$errno);
     //构造post请求的头
     $header = "POST /mobile/try.php HTTP/1.1\r\n";
     $header .= "Host:127.0.0.1\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 $line;
              }
      }
fclose($fp);
?>

还可以使用php类HttpClient
