Data structures in PHP 5.3

In the programming world there are quite a few well understood and explored data structures. Which are commonly used in tons of applications, still the only things PHP offered till 5.3 in regards to structuring data were arrays (more precise: hash tables) and objects. So people had to either abuse them for other structures or implement the structures themselves on top of these. Thanks to Etienne things now are changing and PHP's Standard PHP Library (SPL) extension will offer quite a few standard implementations of data structures. The implemented data structures are implemented using these classes:

* SplDoublyLinkedList
* SplStack
* SplQueue (SplPriorityQueue)
* SplHeap (SplMinHeap, SplMaxHeap)
* SplFixedArray
