Doctrine Cache Extension

The Doctrine Cache extension adds the following features to Doctrine Cache implementation:

• Default lifetime
• Fetch with a namespace
• Save with a namespace
• Cache invalidation through namespace strategy

Installation

The easiest way to install DoctrineCacheExtension is via composer.

Create the following composer.json file and run the php composer.phar install command to install it.

{
    "require": {
        "openclassrooms/doctrine-cache-extension": "*"
    }
}

<?php
require 'vendor/autoload.php';

use OpenClassrooms\DoctrineCacheExtension\CacheProviderDecorator;

//do things

Usage

Instantiation

OpenClassrooms CacheProviderDecorator needs a Doctrine CacheProvider to be instantiated.

$cacheProvider = new ArrayCache();
$cacheProviderDecorator = new CacheProviderDecorator($cacheProvider);

A factory can be used to accomplish this.

$factory = new CacheProviderDecoratorFactory();
$cacheProvider = $factory->create('array');

Default lifetime

Specify lifetime in the constructor:

$cacheProviderDecorator = new CacheProviderDecorator($cacheProvider, 100);
$cacheProviderDecorator->save($id, $data);

Or via the factory:

$cacheProvider = $factory->create('array', 100);

Or specify a default lifetime for all the cache providers:

$factory = new CacheProviderDecoratorFactory();
$factory->setDefaultLifetime(100);

Fetch with namespace

$data = $cacheProviderDecorator->fetchWithNamespace($id, $namespaceId);

Save with namespace

// Namespace and life time can be null
$data = $cacheProviderDecorator->saveWithNamespace($id, $data, $namespaceId, $lifeTime);

Cache invalidation

$cacheProviderDecorator->invalidate($namespaceId);
