On the TutsPlus.com site today they've posted a new tutorial spotlighting one of the components that makes up the Symfony framework, the Symfony Cache Component - and how you can use it to improve the performance of your applications.

Today, I'll show you the Symfony Cache component, an easy way to add caching to your PHP applications. This helps improve the overall performance of your application by reducing the page load time.

[...] In this article, we'll explore how you can unleash the power of the Symfony Cache component. As usual, we'll start with installation and configuration, and then we'll go on to explore a few real-world examples in the latter half of the article.

The tutorial starts with a few basic terms you'll need to be familiar with to use the component. From there it's straight into the installation and configuration of the component. Code is then included showing a more "real world" example of caching several different kinds of data, fetching it and setting expiration times. It then walks through each line of the code explaining how it works and more context about what's happening behind the scenes.
