myhttp类 php使用fsockopen实现稳定的HTTP连接(转)

网上找到一个用fsockopen函数实现http请求的类，感觉不错。

            $this->URI=$uri;
            $this->Method=$method;
            $this->SendDate=$query;
            $this->HttpServer=$server;

        }
 
        public function send(){
            $this->Method=strtoupper($this->Method);
            if($this->HttpServerIP=="")$this->HttpServerIP = $this->HttpServer;

                $headers .= "$str\n";
 
            $body = "";
            while (!feof($sock))
                $body .= fgets($sock, 4096);
            fclose($sock);
            $this->responseText=$body;
        }
    }

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;
?>
