PHP用curl伪造IP和来源

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://localhost/ajax.php");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8')); //伪造IP
curl_setopt($ch, CURLOPT_REFERER, "http://www.gosoa.com.cn/ "); //伪造来路
curl_setopt($ch, CURLOPT_HEADER, 1);
$out = curl_exec($ch);
curl_close($ch);

<?php
function recordUrlKeywords($url) {
$spider = array('baidu.'=>'百度', 'google.'=>'谷歌', 'soso.'=>'搜搜', 'sogou.'=>'搜狗', 'www.so.com'=>'360');
$q = array('百度'=>'/wd=([^&]*)/i', '谷歌'=>'/q=([^&]*)/i', '360'=>'/q=(.*)/i', '搜狗'=>'/query=([^&]*)/i', '搜搜'=>'/w=([^&]*)/i');
// http://3aj.cn/
foreach($spider as $k=>$v) {
   if (strpos($url, $k)) {
preg_match("{$q[$v]}", $url, $b);
     if (($v=='搜搜') || ($v=='搜狗')) {
$keywords = iconv('GBK', 'UTF-8', urldecode($b[1]));
     } else {
$keywords = urldecode($b[1]);
     }
       echo "来自{$v}的关键字:".$keywords;
   }
 }
}
$url = $_SERVER['HTTP_REFERER']; // 获取网站来源地址
recordUrlKeywords($url);
?>
