On WebSpeaks.in today there's a recent post that introduces you to something more and more applications are using - especially frameworks - method chaining in PHP OOP apps.

In this article we will learn an advanced OOPS programming concept in PHP known as Method chaining.

They create a simple class, a Person, and show the difference between calling several methods on the created object versus a method chained example that calls all three, making updates to the object itself ($this). There's also a bit more complicated example with three different classes in the mix.
