CURL方式：
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,"http://www.yyyy.com");
curl_setopt ($ch, CURLOPT_REFERER,"http://www.xxxx.com/");
curl_exec ($ch);
curl_close ($ch);
SOCKET方式：
$server ='www.yyyy.com';
$host ='www.yyyy.com';
$target ='index.php';
$referer ='http://www.xxxx.com/';// Referer
$port =80;
$fp = fsockopen($server, $port, $errno, $errstr,30);
if(!$fp){
echo"$errstr ($errno)\n";
}else{
$out ="GET $target HTTP/1.1\r\n";
$out .="Host: $host\r\n";
$out .="Referer: $referer\r\n";
$out .="Connection: Close\r\n\r\n";
fwrite($fp, $out);
while(!feof($fp)){
echofgets($fp,128);
}
fclose($fp);
}
file_get_contents方法：
$opt=array('http'=>array('header'=>"Referer: $refer"));
$context=stream_context_create($opt);
$file_contents = file_get_contents($url,false, $context);
通過上面的代碼檩坚，我們就把referer地址偽裝為http://www.xxxx.com，你可以寫一段代碼：
$_SERVER['HTTP_REFERER'];
查看到這個referer地址，就是這么簡單碘勉，所以referer也不是什么可靠的數(shù)據(jù)了睦袖。
