Array notation is fine, but it can look a bit clunky when you're working with complex structures. [...] Casting the array to an object allows us to use object notation (->) and makes the code more readable.

He includes examples of the casting, showing the difference between the array and object notations including a method for creating an object based on a simple array that has basic properties built in. This sort of transformation can be useful if you want consistency through out the application - just passing objects with their properties rather than arrays.

My last post about back to basics covered reverse polish notation including a link to a RPN parser which I wrote to allow people to learn by example (best way in my opinion and in yours). The post got quite long and the PHP code was not really relevant to the subject so I have decided to include in this separate post instead.

There's two parts to the post - a pseudo-code explanation that an overview of how things work and the actual code, a block of code (in the 30 line area) that runs through each item and, based on a token, pushes the value into the array differently.

There has been some recent activity on the PHP Developer mailing list about the addition of JSON into the PHP Core. After reading the thread, I did a little research on JavaScript Object Notation (JSON). Here is a great website to read more about it.
