Variables are the simplest concept in programming. Or are they? We'll explore variables in PHP and how they work under the hood. We'll see how references work, and the difference between "variable references" and "object references".

This is the third of what I hope to be many videos on the topic of programming. Plenty of future ones are planned, but the topics, order and even if they happen is completely up to you! I want your feedback on the concept. Is it something worth pursuing? Any topics you'd like to see? Any other comments about the concept?
