PHP作为客户端访问socket的一个简单实现类

<?php

ob_implicit_flush();

const SOCKET_SERV_HOST = "localhost";

private $host=SOCKET_SERV_HOST;
private $port=SOCKET_SERV_PORT;

public function __set($name,$value){

}

if(!$this->socket){

}
// set no data read timeout

}

public function send($data){

if(!$result){

}
}
