本文章介紹了一個簡單的關于php入門篇-緩存技術簡單應用,有需要的朋友可以看看,這里是利用了ob_start(); ob_end_flush(); 來實例的,代碼如下:
- <?php
- // define the path and name of cached file
- $cachefile = 'cached-files/'.date('M-d-Y').'.php';
- // define how long we want to keep the file in seconds. I set mine to 5 hours.
- $cachetime = 18000;
- // Check if the cached file is still fresh. If it is, serve it up and exit.
- if (file_exists($cachefile) && time() - $cachetime < filemtime($cachefile)) {
- include($cachefile);
- exit;
- }
- // if there is either no file OR the file to too old, render the page and capture the HTML. //開源代碼Vevb.com
- ob_start();
- ?>
- <html>
- output all your html here.
- </html>
- <?php
- // We're done! Save the cached content to a file
- $fp = fopen($cachefile, 'w');
- fwrite($fp, ob_get_contents());
- fclose($fp);
- // finally send browser output
- ob_end_flush();
- ?>
