Improving performance using the cache

The cache software design pattern is where you store a result that takes a long time to generate. This could take the form of a lengthy view script or a complex database query. The storage destination needs to be highly performant, of course, if you wish to improve the user experience of website visitors. As different installations will have different potential storage targets, the cache mechanism lends itself to the adapter pattern as well. Examples of potential storage destinations include memory, a database, and the filesystem.

How to do it...

As with a couple of other recipes in this chapter, as there are shared constants, we define a discreet Application\Cache\Constants class:
```
<?php namespace Application\Cache; ...
```
