Anthony Ferrara is back again with another installment in his "Programming with Anthony" video series. In this new episode he takes a loot at iterators in PHP and how they can be used effectively.

Today's Programming With Anthony video focuses on the concept of Iterators. We'll look at the abstraction that they represent, how they can be used and some of the benefits of using them. When used correctly, Iterators can lead to very efficient, flexible and clean code.

You can also watch the video directly on YouTube and check out the rest of the series in his playlist. Other topics include dependency injection, boolean logic and prepared statements.
