Basically, you can do something like this to cache your navigation for 24 hours at a time:

$path_to_cache = './navigation.html'; if(file_exists($path_to_cache) && filemtime($path_to_cache) > strtotime("-24 hours")){ include($path_to_cache); } else { // query MySQL // generate navigation HTML file_put_contents($path_to_cache, $nav_html); echo $nav_html; }
