　　网上找到一个用fsockopen函数实现http请求的类，感觉不错。

输入参数的方法有两种，在创建类的时候同时输入参数和先创建类，慢慢输入参数。相关例子分别为test，test2，该类同时支持get,post的方法。


<?php
include("myHttp.class.php");
$test = new myHttp();
$test -> URI = "/index.php";
$test -> HttpServer = "www.miaoqiyuan.cn";
$test -> Method = "post";
$test -> SendDate ="s=myhttp";
$test -> send();
echo $test -> responseText;
$test2 = new myHttp('/index.php','get','s=myhttp','www.miaoqiyuan.cn','80','',30);
$test2 -> send();
echo $test2 -> responseText;
?>
