PHP通过socket使用异步post提交

$fp = fsockopen('http://192.168.2.186',8289,$errno,$errstr,30);
if(!$fp){
  return;
}else{
  stream_set_blocking($fp,0);
  $http = "POST /sdkMethod/setIpMeetInfo.php?act=upload&uploadtype=2 HTTP/1.1\r\n";
  $http.="Host:192.168.2.186:8289\r\n";
  $http.="Content-type:application/json;charset=utf-8\r\n";
  $http .= "Content-length:".strlen($this->ipMeetInfo)."\r\n";
  $http.="Connection:Close\r\n\r\n";
  fwrite($fp,$http);
  fwrite($fp,'json数据');
  fclose($fp);
}
