Programming With Anthony - References In PHP

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?

Awesome! Excellent teaching abilities. If there weren't so many other PHP instructions on Youtube, you'd have far more views and subscribers. I'm spreading the word :) +1

As a novice looking to understand referencing, i found this too verbiage. Thanks for those have learned though.

Excited to watch this since i haven't used references much or at all in personal home page

"clone()" only takes a shallow copy of course. I presume to avoid circular referencing. Something to note if you have properties that point to other references.
