<?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. 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(); ?> | |
