In his latest post Chris Morrell introduces a project he's been working on to help with his dependency injection needs - Zit, an object-oriented dependency injection container similar to the Pimple DIC from Fabien Potencier.
I'll admit right now that I'm fairly new to the world of dependency injection containers. I usually do my dependency injection "manually" and have always thought that there must be a better way. Then I came across Pimple, which is a wonderfully simple solution to the problem. The only thing about it is that I hate its array-oriented interface. Something about $container['session_storage'] rubs me the wrong way.
The Zit tool should be very familiar to any user of Pimple, as it implements similar functionality, just in an OOP kind of way. He includes some example code in the post showing how to create a database connection object and inject it into the Zit container. You can find the latest code for the tool over on github.
