PHP使用curl模拟ip和来源进行访问

server.php

<?php
$client_ip = getip();
$referer = getreferer();
 
$allow_ip = '192.168.1.100';
$allow_referer = 'http://www.zhansanjie.com';
 
if($client_ip==$allow_ip && strpos($referer, $allow_referer)===0){
    echo 'allow access';
}else{
    echo 'deny access';
}
 
// 获取访问者ip
function getip(){
    if(!empty($_SERVER['HTTP_CLIENT_IP'])){
        $cip = $_SERVER['HTTP_CLIENT_IP'];
    }elseif(!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
        $cip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    }elseif(!empty($_SERVER['REMOTE_ADDR'])){
        $cip = $_SERVER['REMOTE_ADDR'];
    }else{
        $cip = '';
    }
    return $cip;
}
 
// 获取访问者来源
function getreferer(){
    if(isset($_SERVER['HTTP_REFERER'])){
        return $_SERVER['HTTP_REFERER'];
    }
    return '';
}
