Installation
$ composer install dc/cache
Or add it to composer.json
:
"require": { "dc/cache": "0.*", }
$ composer install
This package suggests dc/cache-memcache
, which is the only implementation at this point.
Getting started
This is just an interface. You probably should install dc/cache-memcahe
or write your own implementation to the interface.
When you have, you can use the interface like this:
$cache = new \SomeImplementation(); $cache->set('foo', 'bar'); echo $cache->get('foo'); // prints bar
A common pattern is that you want a specific value from the cache, and if it is a cache miss, you want to produce it:
echo $cache->getWithFallback('foo', function() { return 'bar'; }); // prints bar $cache->get('foo'); // now also prints bar
This syntax works with any callable, not just closures.
You can also use the return value to determine the validity.
$foo = $cache->getWithFallback("foo", function($x) { return ["foo" => $x, "expires" => \DateInterval($x)]; }, function($result) { return $result["expires"]; });
