本文章介绍了一个简单的关于php入门篇-缓存技术简单应用,有需要的朋友可以看看哦,这里是利用了ob_start(); ob_end_flush(); 来实例的。
代码如下 复制代码

// 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() - $cachetime include($cachefile);
exit;
}
// if there is either no file OR the file to too old, render the page and capture the HTML.
ob_start();
?>

output all your html here.

// 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();
?>
