简易的模拟IP以及伪造成百度蜘蛛去请求某个URL。  
```php  
function curl_get_contents($url, $ip)  
{  
    $ch = curl_init();  
    $isSSL = substr($url, 0, 8) == 'https://' ? true : false;  
    $headerPara = array(  
        "Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",  
        "Accept-Language:zh-CN,zh;q=0.9",  
        'Referer: https://www.baidu.com/s?wd=%E7%99%BE%E5%BA%A6&rsv_spt=1&rsv_iqid=0xe5a39f3b0003c303&issp=1&f=8&rsv_bp=0&rsv_idx=2&ie=utf-8&tn=baiduhome_pg&rsv_enter=1&rsv_sug3=6&rsv_sug1=4&rsv_sug7=100',  
        'CLIENT-IP: ' . $ip,  
        'X-FORWARDED-FOR: ' . $ip  
    );

curl_setopt($ch, CURLOPT_URL, $url);  
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headerPara);  
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);  
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; Baiduspider/2.0; +http://www.baidu.com/search/spider.html)');  
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);  
    if ($isSSL) {  
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);  
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);  
    }  
    $result = curl_exec($ch);  
    curl_close($ch);  
    return $result;  
}

function randip(){  
    return rand(13, 255) . '.' . rand(13, 255) . '.' . rand(13, 255) . '.' . rand(13, 255);  
}
