We already know what to write when we want to use some PHP code, how to set a variable, and how to print things. Like most languages, PHP also has functions that make it easier to do more complex tasks. Instead of you needing to figure out all of the logic to accomplish something, like randomizing a number, you can just use an existing PHP function, like rand(), to do the work for you. In this lesson, you'll learn how to use a function, what arguments are and how they work, and use some examples in our demo site code.
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?
