Installation

If you are working on an Asgard project you don't need to install this library as it is already part of the standard libraries., _(*4)

composer require asgard/cache 0.*

, _(*5)

Usage in the Asgard Framework

The cache is available through the service:, _(*6)

$cache = $container['cache'];

To change, the cache driver in an Asgard application, edit the web/index.php file., _(*7)

, _(*8)

Usage outside the Asgard Framework

$cache = new \Asgard\Cache\Cache(new \Doctrine\Common\Cache\Cache);

, _(*9)

Array implementation

You can access the cache like an array :, _(*10)

$value = $cache['key'];
$cache['key'] => $value;
isset($cache['key']);
unset($cache['key']);

, _(*11)

Default result

If the cache cannot fetch you key, it will return and store the default value. The default value can also be a callback, in which case the result will be returned and stored:, _(*12)

$cache->fetch('key', 'default');
#or
$cache->fetch('key', function() {
    return 'default';
})

, _(*13)

NullCache

NullCache lets you use the cache without concern for its activation. The values will not be stored but the code using the cache will be same either way:, _(*14)

$cache = new \Asgard\Cache\Cache(new \Asgard\Cache\NullCache());
$res = $cache->fetch('home', function() {
    return '<h1>Home</h1>';
});

If the cache driver was different, the result would be stored and used the next time the cache is called., _(*15)

, _(*16)
