PHP 緩衝內容為HTML並輸出

#$_time : 緩衝時間<br />#$dir : 緩衝路徑<br />function cache_start($_time, $dir)<br />{<br /> $cachefile = $dir.'/'.sha1($_SERVER['REQUEST_URI']).'.html';<br /> $cachetime = $_time;<br /> ob_start();<br /> if(file_exists($cachefile) && (time( )-$cachetime < filemtime($cachefile)))<br /> {<br /> include($cachefile);<br /> ob_end_flush();<br /> exit;<br /> }<br />}<br />function cache_end($dir)<br />{<br /> $cachefile = $dir.'/'.sha1($_SERVER['REQUEST_URI']).'.html';<br /> $fp = fopen($cachefile, 'w');<br /> fwrite($fp, ob_get_contents());<br /> fclose($fp);<br /> ob_end_flush();<br />}

將cache_start函數放在頁首，cache_end放在頁末
