Silex Cache Service Provider

The Silex Cache service provider allows you to use several PHP opcode cache in your Silex application.

Installation

To enable it, add this dependency to your composer.json file:

{
    "require": {
        "moust/silex-cache": "~2.0"
    }
}

Parameters

• cache.options: Array of cache options.
  • driver: The cache driver to use. Can be any of: apc, array, file, memcache, memcached, xcache, redis, wincache.
  • cache_dir: Only relevant for file cache driver, specifies the path to the cache directory
  • memcache: Only relevant for memcache cache driver, provide the Memcache instance to use. If not defined, a default Memcache object will be instanciated. See the Memcache documentation for additional informations : PHP: Memcache - Manual
  • memcached: Only relevant for memcached cache driver, provide the Memcached instance to use. If not defined, a default Memcached object will be instanciated. See the Memcached documentation for additional informations : PHP: Memcached - Manual
  • redis: Only relevant for redis cache driver, provide the Redis instance to use. If not defined, a default Redis object will be instanciated. See the PhpRedis documentation for additional informations : PhpRedis

Registering

$app->register(new Moust\Silex\Provider\CacheServiceProvider(), array(
    'cache.options' => array(
        'driver' => 'apc'
    )
));

Usage

The Cache provider provides a cache service. Here is a usage example:

// stores a variable
$app['cache']->store('foo', 'bar');
// stores a variable with a 1 minute lifetime
$app['cache']->store('foo', 'bar', 60);
// fetch variable
echo $app['cache']->fetch('foo');
// delete variable
$app['cache']->delete('foo');
// clear all cached variables
$app['cache']->clear();

Using multiple caches

The Cache provider can allow access to multiple caches. In order to configure the cache drivers, replace the cache.options with caches.options. caches.options is an array of configurations where keys are cache names and values are options:

$app->register(new Moust\Silex\Provider\CacheServiceProvider(), array(
    'caches.options' => array(
        'apc' => array(
            'driver' => 'apc'
        ),
        'filesystem' => array(
            'driver' => 'file',
            'cache_dir' => './temp'
        ),
        'memory' => array(
            'driver' => 'array'
        ),
        'memcache' => array(
            'driver' => 'memcache',
            'memcache' => function () {
                $memcache = new \Memcache;
                $memcache->connect('localhost', 11211);
                return $memcache;
            }
        )
    )
));

The first registered cache is the default and can simply be accessed as you would if there was only one. Given the above configuration, these two lines are equivalent:

$app['cache']->store('foo', 'bar');

$app['caches']['apc']->store('foo', 'bar');
