cacheSys
Simple PHP caching system for raw data or rendered output., (*1)
Installing
Composer is the preferred installation method. https://packagist.org/packages/andrewsauder/cachesys, (*2)
composer require andrewsauder/cachesys
Useage
All of the samples below will assume that you add a use statement inside of your namespace referencing cacheSys., (*3)
<?php
namespace MyVendorNamespace;
use andrewsauder;
If you opt not to add a use statement, you must reference the cacheSys methods by it's fully qualified class name. Ie:, (*4)
\andrewsauder\cacheSys::get( 'cacheName', 'cacheKey' );
Retrieving and Create Cache
This is the core useage of cacheSys. I like to think of it as a wrapper for any complex logic that slows requests down., (*5)
$employee = cacheSys::get( 'employees', 712 );
if( $employee===false ) {
//do heavy lifting to create $employee
$employee = 'Andrew';
cacheSys::put( 'employees', 712, $employee );
}
var_dump( $employee );
Of course, you always need to make sure that your cached data remains relevant. To do this you can make use of the max age parameter of the get method, (*6)
/* get the cached copy of employee 712
* but return false if the cache was created
* more than 86,400 seconds (24 hours) ago
*/
$employee = cacheSys::get( 'employees', 712, 86400 );
Delete Cached Item
You can also delete a specific cached item on demand., (*7)
cacheSys::deleteCachedItem( 'employees', 712 );
Delete Cache Category
Or delete an entire cache category. For example, if you wanted to delete all employees instead of just one, you can delete the entire category instead, (*8)
cacheSys::deleteCachedCategory( 'employees');
