A bridge to convert CakePHP Cache to SimpleCache (PSR16)

Why build this?

In a few of my CakePHP apps I make use of 3rd party libraries that require a PSR-16 compatible cache engine. This bridge allows me to reuse the Cache Engines and Cache configs already available within my CakePHP application and eliminates the need of having to build 2 different sets of Cache management libraries.

Isn't this already in CakePHP 3.7 ?

No. CakePHP 3.7 brings with it a PSR-16 CacheEngine; meaning you will be able to decorate a PSR-16 object to implement Cake\Cache\CacheEngine methods. What this bridge offers is the ability to go from a Cake\Cache\CacheEngine to PSR-16, not the other way around.

The new SimpleCacheEngine class ( in CakePHP 3.7 ) implements PSR 16 interface and decorates/wraps CacheEngine classes.

Thanks Admad for the clarification.

Examples

Cache::config('short', [
    'className' => 'File',
    'duration' => '+1 hours',
    'path' => CACHE,
    'prefix' => 'cake_short_'
]);

$cache = new Bridge('short');

//setting cache data
$cache->set('some_key', 'some value');

//getting cache data with a default
$value = $cache->get('some_key', 'some default');

//overriding the Cache engine's TTL with an int
$cache->set('some_key', 'some value', 300); //cached for 300 seconds instead of `+1 hours`

//overriding the Cache engine's TTL with a `\DateTimeInterval` ( as per the SimpleCache Interface )
$interval = new \DateTimeInterval('P1Y'); // an interval of 1 year
$cache->set('some_key', 'some value', $interval); //cached for 1 year instead of `+1 hours`

Requirements

• PHP >=5.6
• CakePHP >=3.0

Installation

You can install this library using composer.

The recommended way to install as a composer package:

composer require angelxmoreno/cakephp-simplecache-bridge

Setup

Once you have a cahe configuration defined, you simple have to pass the config name when creating an instance of the Bridge like so:

Cache::config('short', [
    'className' => 'File',
    'duration' => '+1 hours',
    'path' => CACHE,
    'prefix' => 'cake_short_'
]);

$cache = new Bridge('short');
