Predis service provider for the Silex microframework

branch: master
README.md

PredisServiceProvider

This is a service provider for Silex that enables developers to easily connect to Redis by using Predis.

Getting started

Supposing that you have already set up the required dependencies using Composer and the skeleton of your Silex application is ready, now you simply need to register the service provider specifying the parameters and options needed to access Redis:

$app->register(new Predis\Silex\PredisServiceProvider(), array(
    'predis.parameters' => 'tcp://127.0.0.1:6379',
    'predis.options'    => array('profile' => '2.2'),
));

This will register a single Predis\Client instance accessible by your application using $app['predis']. Both predis.parameters and predis.options are optional and accept the same values of the constructor of Predis\Client.

Certain applications might need more than one client to reach different servers or configured with different options such as key prefixing or server profile. In such cases you must use Predis\Silex\MultiPredisServiceProvider and provide a list of clients with their own parameters and options using predis.clients:

$app->register(new Predis\Silex\MultiPredisServiceProvider(), array(
    'predis.clients' => array(
        'first' => 'tcp://127.0.0.1:6379',
        'second' => array(
            'host' => '127.0.0.1',
            'port' => 6380,
        ),
        'third' => array(
            'parameters' => 'tcp://127.0.0.1:6381',
            'options' => array(
                'profile' => 'dev',
                'prefix' => 'silex:',
            ),
        ),
    ),
));

Client instances will be exposed to your application using $app['predis'][$alias] where $alias is the key used to populate the items of predis.clients. You can optionally define a default client by specifying its alias in predis.default_client to make it accessible by invoking methods of Predis\Client directly against $app['predis']. Each client instance will be initialized lazily upon first access.

You can find more details on how to use this provider in the examples directory or the test suite,
