Related to the previous tutorial where we implemented best practices to centralize our configuration, we also want to minimize the number of database connections. We want one connection that every class uses. In this tutorial we'll move the new
PDO() call out of
ShipLoader so that it can be created in a central location and used by everyone. How? By using the same strategy we just learned with configuration. If you want to move something out of a service class, add it as a
__construct() argument and pass it in.
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?
