README

StashSilex is a Silex service provider and session handler for the popular caching library Stash.

Requirements

StashSilex requires PHP version 5.3+, Silex version 1.* and Stash version 0.11+

Install

Via Composer

$ composer require M1/StashSilex

Usage

You use the StashServiceProvider to register the service provider with the usual syntax for registering service providers:

$app->register(new M1\StashSilex\StashServiceProvider());

There's a few options you can use when registering the service provider.

Pools

You can register either one pool using pool.options or multiple using pools.options, this works like the Doctrine Service Provider.

Registering one pool:

$app->register(new M1\StashSilex\StashServiceProvider(), array(
    'pool.options' => array(
        'driver' => 'FileSystem',
        'options' => array(
            'path' => __DIR__.'/../../app/cache',
        ),
    )
));

$item = $app['pool']->getItem('path/to/item');

Registering multiple pools:

$app->register(new M1\StashSilex\StashServiceProvider(), array(
    'pools.options' => array(
        'fs' => array(
            'driver' => 'FileSystem',
            'options' => array(
                'path' => __DIR__.'/../../app/cache',
            ),
        ),
        'mc' => array(
            'driver' => 'Memcache',
            'options' => array(
                'servers' => array(
                    '127.0.0.1', '11211'
                )
            ),
        ),
    ),
));

// same thing
$item1 = $app['pools']['fs']->getItem('path/to/item');
$item1 = $app['pool']->getItem('path/to/item');

$item2 = $app['pools']['mc']->getItem('path/to/item');

You can access your pools through $app['pool'] and $app['pools']['the_key_of_your_pool']. If you have multiple pools, then your first pool registered will be available through $app['pool'].

For example, in the above code, the FileSystem pool will be available through $app['pool'] and $app['pools']['fs'].

Drivers

The driver option is based on the class names for the available drivers, see here for the class names defined by Stash. The driver names are case sensitive.

You can set the driver options through options like so:

$app->register(new M1\StashSilex\StashServiceProvider(), array(
    'pool.options' => array(
        'driver' => 'FileSystem',
        'options' => array(
            'path' => __DIR__.'/../../app/cache',
        ),
    )
));

You can see the full list of the available options for each driver here. The default driver if no driver is defined is the Ephemeral driver.

Logger

You can also set the logger for the pool via the logger option like so:

$app->register(new Silex\Provider\MonologServiceProvider(), array(
    'monolog.logfile' => __DIR__.'/../../app/logs/app/dev.log',
));

$app->register(new M1\StashSilex\StashServiceProvider(), array(
    'pool.options' => array(
        'driver' => 'FileSystem',
        'options' => array(
            'path' => __DIR__.'/../../app/cache',
        ),
        'logger' => 'monolog'
    )
));

The logger is monolog due to the MonologServiceProvider populating $app['monolog']. The logger option is a string which your logger service can be accessed through $app.

For example if you decided to not use Monolog through the service provider (not recommended), you can use your custom logger like so:

$app['mylog'] = $app->share(function($app) {
    $logger = new \Monolog\Logger('mylog');
    $logger->pushHandler(new Monolog\Handler\StreamHandler('/logfile/mylog.log', Logger::INFO));
    return $logger;
});

$app->register(new M1\StashSilex\StashServiceProvider(), array(
    'pool.options' => array(
        'driver' => 'FileSystem',
        'options' => array(
            'path' => __DIR__.'/../../app/cache',
        ),
        'logger' => 'mylog'
    )
));

Sessions

You can choose to handle your sessions through Stash in a couple of different ways.

The first way is via the service provider.

The below creates sessions with defaults:

$app->register(new M1\StashSilex\StashServiceProvider(), array(
    'pool.options' => array(
        'driver' => 'FileSystem',
        'options' => array(
            'path' => __DIR__.'/../../app/cache',
        ),
        'session' => true
    )
));

You can also set the ttl and the session prefix (what namespace it is stored in in stash, more info here) like so:

$app->register(new M1\StashSilex\StashServiceProvider(), array(
    'pool.options' => array(
        'driver' => 'FileSystem',
        'options' => array(
            'path' => __DIR__.'/../../app/cache',
        ),
        'session' => array(
            'prefix' => 'session_name',
            'expiretime' => 3200
        )
    )
));

You can also set the SessionHandler manually via:

$app->register(new M1\StashSilex\StashServiceProvider(), array(
    'pool.options' => array(
        'driver' => 'FileSystem',
        'options' => array(
            'path' => __DIR__.'/../../app/cache',
        )
    )
));

// Without options
$app['session.storage.handler'] = $app->share(function ($app) {
    return new M1\StashSilex\StashSessionHandler($app['pool']);
});

// With options
$app['session.storage.handler'] = $app->share(function ($app) {
    return new M1\StashSilex\StashSessionHandler($app['pool'], array(
        'prefix' => 'session_name',
        'expiretime' => 3200
    ));
});

Recommendations

Instead of setting the options through an array, think about using a config loader like m1/vars, where you can just load the configuration of your pool(s) via a file like so:

# example.yml
pools:
    filesystem:
        driver: FileSystem
        options:
            path: %dir%/../../app/cache
        session:
            prefix: session_name
            expiretime: 3200

$app->register(new M1\Vars\Provider\Silex\VarsServiceProvider('example.yml'), array(
    'vars.options' => array(
        'variables' => array(
            'dir' => __DIR__
        ),
)));
    
$app->register(new M1\StashSilex\StashServiceProvider(), array(
    'pools.options' => $app['vars']['pools']
));

This way makes it so much easier to make small little changes without having to dive into code.
