In this tutorial we're going to add our
$limit variable as an optional argument to our
get_pets() function. We're using this variable in our
if statement, and we're going to look at different ways to supply "true" and "false" using data other than booleans. This allows you to pass in a value and still evaluate true/false. PHP has some conventions for what is true or not, and it's a good idea to understand what these are.
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?
