PHP Server and Browser Cache

I am writing this tutorial to increase speed of your web applications with server and browser cache. With caching your application become super lets come to the details of the procedure of cache.


[wpdm_file id=19]DEMO


You should have writing permission for the caching folder (eg. chmod 666 or 777).
You should add attached value (for example cookie or session value ) for the logged users.
The caching object should be added right after the initialization of cookie session.


// in this case i created the folder "cache" in root

$cache=new CACHE($folder);
// after that.. the rest of the page/scripts

//showing the content

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

1. Server Side Caching


$cache=new CACHE($folder);
$cache->setCacheType(1); //server side caching


2. Client Side (Browser) Caching


$cache=new CACHE($folder);
$cache->setCacheType(2); //client side caching


3. Both (Server and Client) Side Caching


$cache=new CACHE($folder);
$cache->setCacheType(3); //both side caching


4. Logged User Both Side Cache


$cache=new CACHE($folder,2, $_COOKIE['user']); // $_COOKIE['user'] is just an example


cache.php file default settings

private $root=""; // path to the local folder, YOU NEED WRITING PERMISSIONS (chmod 666 or 777)
private $server__cache_time=300; // how long a file will remain cached on browser ( seconds )
private $client__cache_time=150; //how long a file will remain cached on browser ( seconds )
private $cache_type=2; // 0 = no cache , 1 = server side cache, 2 = client side (browser) cache, 3 = both side cache
private $attached_value=""; //useful to COOKIE or SESSION values (for example it may be used for logged users )
private $page;
public $file_name; // the cache file name on server
public $full_file_name; //full file path and name on local server
public $need_update=false; //if true then the content will be saved locally in the path (full_file_name)
public $file_extension="html"; // useful to check the cache content faster
