<?php
$A=trim(urlencode('aaaa'));
$B=trim(urlencode('bbbb'));
$C=trim(urlencode('ccccc'));
$params = "Content-A=$A&Content-B=$B&Content-C=$C";

$length = strlen($params);
$fp = fsockopen("localhost",80,$errno,$errstr,10) or exit($errstr."--->".$errno);
$header  = "POST /2.php HTTP/1.1rn";//一般有post, get这两种 
$header .= "Host:localhostrn";

$header .= $params."rn";

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 == "rn")) { 
             $inheader = 0; 
        } 
        if ($inheader == 0) {
