php用Curl伪造客户端源IP

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://localhost/index.php");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8')); 

//构造IP
curl_setopt($ch, CURLOPT_REFERER, "http://www.111cn.net/ ");   //构造来路
curl_setopt($ch, CURLOPT_HEADER, 1);
$out = curl_exec($ch);
curl_close($ch);

<?php
function getClientIp() {
    if (!empty($_SERVER["HTTP_CLIENT_IP"]))
        $ip = $_SERVER["HTTP_CLIENT_IP"];
    else if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))
        $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
    else if (!empty($_SERVER["REMOTE_ADDR"]))
        $ip = $_SERVER["REMOTE_ADDR"];
    else
        $ip = "err";
    return $ip;
}

echo "IP: " . getClientIp() . "";
echo "referer: " . $_SERVER["HTTP_REFERER"];

echo "IP: " . getClientIp() . "";
echo "referer: " . $_SERVER["HTTP_REFERER"];

function rmkdir($path, $mode = 0755) {
    $path = rtrim(preg_replace(array("/\\/", "//{2,}/"), "/", $path), "/");
    $e = explode("/", ltrim($path, "/"));
    if(substr($path, 0, 1) == "/") {
        $e[0] = "/".$e[0];
    }

            return false;
        }
        $cp .= "/".$e[$i];
    }
    return @mkdir($path, $mode);
}

?>

<?php
function mkdir_r($dirName, $rights=0777){
    $dirs = explode('/', $dirName);
    $dir='';
    foreach ($dirs as $part) {
        $dir.=$part.'/';

Tested and works ;)

function mkdirs($dir)

    {

        if(!is_dir($dir))

        {

            if(!mkdirs(dirname($dir))){

                return false;

            }

            if(!mkdir($dir,0777)){

                return false;

            }

        }

        return true;

    }

    function rmdirs($dir)

    {

        $d = dir($dir);

        while (false !== ($child = $d->read())){

            if($child != '.' && $child != '..'){

                if(is_dir($dir.'/'.$child))

                rmdirs($dir.'/'.$child);

                else unlink($dir.'/'.$child);

            }

        }

        $d->close();

        rmdir($dir);

    }

项目用到临时写的。待完善
