PHP Tutorial: Generators and Iterators - Quick Guide

Generators and Iterators are two powerful features of PHP and other programming languages such as Java, Python, etc. In this tutorial video, I'll be covering the Generators and Iterators.
This a quick guide, I'll be covering the basics, and how they can be used to make code more efficient and even more readable. After watching this video, you'll better understand these two features and you should be able to use them to your advantage!

at 6:02 , how did the $myIterator object started behaving like an array? am i missing something? please shade light on this.

[@DeskNook]

Check out 2:21 (Example: Iterator OOP)

[@GonzaloMassa]

So ArrayIterator won't check if current() is using a valid key, but your MyIterator class didn't check that and it worked with a foreach loop... what am I missing?

[@DeskNook]

For the current() function it will validate the current position of the key too
For MyIterator which is an implementation of the Iterator interface, validity gonna check by valid() method, the same thing for ArrayIterator
