note 106275 added to function.ob-start

It's easy to add a function that caches the whole page you're going to generate so resources are saved. I wrote it in a file called "cacheable.php", and I included in each file that I want to be cached. It cannot manage files with ob_start inside. Here is the code: file "cacheable.php": ---------------------------------- <?php global $cachefile; $cachefilename = urlencode($_SERVER['REQUEST_URI'])."-".md5($_SERVER['REQUEST_URI']); $cachefile = sys_get_temp_dir ().DIRECTORY_SEPARATOR.$cachefilename.'.cache'; // How long to keep cache file? $cachetime = 60*5; //5min // Is cache file still fresh? If so, serve it. if (file_exists($cachefile) && time() - $cachetime < filemtime($cachefile)) { readfile($cachefile); exit; } function cacheOutputtoFile() { global $cachefile; $webpage = ob_get_contents(); if ($fp = fopen($cachefile, 'w+')) { if (flock($fp, LOCK_EX)) { // do an exclusive lock ftruncate($fp, 0); // truncate file //compress unnecesary spaces $busca = array('/\>[^\S ]+/s','/[^\S ]+\</s','/(\s)+/s'); $reemplaza = array('>','<','\\1'); $webpage = preg_replace($busca, $reemplaza, $webpage); fwrite($fp, $webpage); fclose($fp); } } echo $webpage; } ob_start(); register_shutdown_function("cacheOutputtoFile"); //note you must use register_shutdown_function instead of using "cacheOutputtoFile" as parameter of ob_start as socket is already closed when callback function is called, then the client not get the echo $webpage output. ---------------------------------- usage: require_once(realpath(dirname(__FILE__).DIRECTORY_SEPARATOR).DIRECTORY_SEPARATOR."cacheable.php"); ---------------------------------- ---- Server IP: 80.64.47.13 Probable Submitter: 147.84.200.85 ---- Manual Page -- http://www.php.net/manual/en/function.ob-start.php Edit -- https://master.php.net/note/edit/106275 Del: integrated -- https://master.php.net/note/delete/106275/integrated Del: useless -- https://master.php.net/note/delete/106275/useless Del: bad code -- https://master.php.net/note/delete/106275/bad+code Del: spam -- https://master.php.net/note/delete/106275/spam Del: non-english -- https://master.php.net/note/delete/106275/non-english Del: in docs -- https://master.php.net/note/delete/106275/in+docs Del: other reasons-- https://master.php.net/note/delete/106275 Reject -- https://master.php.net/note/reject/106275 Search -- https://master.php.net/manage/user-notes.php
