In this PHP tutorial we're going to update some information in our ship object and see another way that objects are different from arrays—objects are always passed by reference. We need to add a new feature to our app so that after the battle we can display the final health of the battling ships. One will be zero or negative, but how much health did the other have left? Let's take a look at how we can update the ships to reflect their new health after a battle.
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?
