Learn PHP The Right Way - Full PHP Tutorial For Beginners & Advanced - PHP Iterators & Iterable Type - Iterate Over Objects - Full PHP 8 Tutorial

In this lesson, you will learn what iterators are & how to work with them in PHP. It may sound scary but it's actually pretty simple. With iterators you can define how you want your objects to be iterated on, by default when you iterate over objects in PHP it will iterate on visible properties on the object but sometimes you may want to iterate on a specific property of the object instead. Learn what Iterator, IteratorAggregate & Traversable interfaces are, what iterable data type is & how to implement a basic collection pattern that you might be familiar with from frameworks like Laravel.
