Head.php

phpdefine('CACHE_EXPIRE',1800);  //設定到期時間define('CACHE_PATH',$_SERVER['DOCUMENT_ROOT'].'/cache/'); //設定緩衝目錄define('REFRESH_EXPIRE',10);  is_dir(CACHE_PATH) or mkdir(CACHE_PATH,0777);
//該方法是獲得使用者的重新整理次數，如果使用者連續兩次重新整理，那麼就顯示最新內容function refreshTimes(){    $currentUrl='http://'.$_SERVER["HTTP_HOST"].$_SERVER['REQUEST_URI'];    if(isset($_COOKIE['refreshTimes'])){        $cookArray=explode("\t",$_COOKIE['refreshTimes']);        if(isset($cookArray[1]) and $_SERVER['REQUEST_TIME'] - (int)$cookArray[1] < REFRESH_EXPIRE and isset($cookArray[0]) and $cookArray[0] == $currentUrl){            setcookie('refreshTimes',$currentUrl."\t".$_SERVER['REQUEST_TIME']."\t".(string)((int)$cookArray[2]+1),0,'/');            return (int)$cookArray[2];        }else{            setcookie('refreshTimes',$currentUrl."\t".$_SERVER['REQUEST_TIME']."\t1",0,'/');        return 0;        }    }else{        setcookie('refreshTimes',$currentUrl."\t".$_SERVER['REQUEST_TIME']."\t1",0,'/');        return 0;    }} $key = md5($_SERVER['REQUEST_URI']);$path = CACHE_PATH.$key;if(is_file($path) and filemtime($path)+CACHE_EXPIRE > $_SERVER['REQUEST_TIME'] and refreshTimes() == 0 ){    readfile($path);    exit();}ob_start();?>
