To wrap things up with our app, the last bit of housekeeping is to make one container responsible for creating every service object, like PDO, but also
BattleManager. The problem is that if we called
$container->getPDO() twice on the same request, we'd still end up with multiple
PDO objects, and so, multiple database connections. Ok, if we're careful, we can avoid this. We can do better though—let's guarantee that only one
PDO object is ever created. We did this previously in
ShipLoader, so now we'll move this into our container.
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
Lets go ahead and get started shall we?
