README
Kash is a general purpose caching library that is used to cache various values using a variety of different drivers to accomplish this.
- Database results
- User sessions
- API Calls
Features
- Fast
- Supports
- Filesystem
- APC
- Redis
- Memcached
- PDO
- Null
- Extra drivers that are able to support multiple backends
- Uses PSR-3 standard for logging
- Heavily Tested, Commented, and Quality Controlled
Installation
Composer (Preferred)
This assumes you have composer installed. Once you do that please run
composer.phar require "kash/kash:*"
Usage
<?php // Configure the pool with a driver $driver = new \Kash\Driver\ArrayDriver(); $pool = new \Kash\CachePool($driver); // Use to enable logging, $logger is a PSR-3 compatible logger //$pool->setLogger($logger); // Get an item base on a unique key. If the item does // not exist, it creates one for you /** @var \Kash\CacheItemInterface */ $item = $pool->getItem('example_key'); if (!$item->isHit()) { // ... do stuff, put results into $value $item->set($value); // Expires in 300 seconds from now $item->setExpiration(300); // Save the item to your cache $pool->save($item); } // $result is whatever you had it set to $result = $item->get(); // Delete the item from the cache $pool->deleteItems(array($item)); // Clear the backend cache of all items $pool->clear();
Configure Kash as a Service with Symfony2
Edit your services.xml
file.
<service id="cache_driver" class="Kash\Driver\ArrayDriver" /> <service id="cache_pool" class="Kash\CachePool"> <argument type="service" id="cache_driver" /> <call method="setLogger"> <argument type="service" id="logger" /> </call> </service>
This will set up Kash and use Monolog as the logger or whatever you have setup as the logging service. You can change the driver class to whatever driver you want.
When you need to use the caching service, simple grab it out of the container.
// Inside your controller, inside an action $pool = $this->get('cache_pool');
Core Concepts
Items
Items are the smallest unit that can be cached. This would include the results from an API call or possible just a simple value. Items are what you will use to cache data and check expiration times.
Pools
Items go into and come out of a pool. The pool uses Drivers to talk with various Backends.
Drivers
Drivers are used to communicate with cache Backends such as a filesytem, database, etc. The only know of the Backend they need to communicate with and that they are given CacheItem's to find and persist.
Backends
Backends are anything that is used to store cached items. These include things such as a filesystem up to Redis and everything in between.
Drivers
NullDriver
The NullDriver
does not cache any data.
ArrayDriver
This driver caches data in an array
. It does not persist data, but you are
able to set values and expire items.
Usage
<?php $driver = new \Kash\Driver\ArrayDriver(); $pool = new \Kash\CachePool($driver);
FilesystemDriver
Caches data to a filesystem.
Creating Your Own Driver
All drivers MUST implement the DriverInterface. The documentation for what is expected is documented in this file. Once you have your driver class created you will just inject it into the CachePool when you create it. Easy! For some examples please look at some of the included drivers code.
API Documentation
API docs are generated using phpDocumentor. To generate documentation for this project, please run:
phpdoc -d src -t build/api-docs
Testing
PHPUnit is used as the testing framework. If you want to run tests, just run
phpunit
.
phpunit
