Computaria\Tardis: Cache made easier

Build Status

Cache stuff with almost no modification on your code:


use Computaria\Tardis;
use MyApp\Repository;

$apc = new Doctrine\Common\Cache\ApcCache;
$tardis = Tardis\Factory::grow($apc);

$slowRepository = new Repository\Country;
$fastRepository = $tardis->cacheCallsFrom($slowRepository);

$brazil = $fastRepository->findByCode('BR');

Requirements: PHP >= 5.5

What happened above:

  1. $apc is our cache storage.
  2. $tardis is a factory of proxies, caching into $apc.
  3. $tardis->cacheCallsFrom() creates a new object which will cache and retrieve results from it.

What cache storages are available?


Tardis limitations

  • We can't cache final classes.
  • We only cache public method calls.
  • Methods which accept non-serializable arguments can't be cached auto-magically.


Will the cache-enabled object Tardis create be of the same instance from the original object?

Yes. The object created will be from a new class extending your original class.

Isn't creating a class on the fly expensive and slow?

Yes, although not as slow as you might think and it is only a once in a time operation.

How are you sure of what cache key to retrieve?

To create a cache key we use Full\Class\Name::methodName and serialize all its arguments, in order to have a unique identity to that call.

If a method, of the same class and with the same arguments, return different things you are in trouble.

How do I expire a cache entry?

You should use Doctrine\Cache, or your own cache storage configuration for that.

We are working on solutions for that. Have an idea? Help us!

You can’t perform that action at this time.
