We've seen how we can create variables and set each to a string or a number. We've also used functions like rand and
strtoupper to return numbers and strings. Let's talk about a third type of variable in PHP: an array. An array represents a group of things, like 5 random numbers or 3 strings. They're a really important type of data in PHP, and you'll be using them often. In this lesson we'll create an array, and then use foreach to loop through the array so we can complete a repetitive action for each item in the array. We'll also look at how you can access a specific item in an array, explaining keys and indexes.
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?
