Simple way to understanding implementation of SHA-3 Keccak hashing algorithm

Question

I have been looking for references about the algorithm keccak on the internet, but none make me understand.

Here are some links that I found.

Is there a way to understand the implementation or algorithm keccak easily? Is there a code on the PHP implementation for this algorithm?

Someone wrote [an extension](https://github.com/jedisct1/keccak-php) for it. — Ja͢ck, May 05 '14 at 09:57
Yes, but how to understand this algorthm and how to implement psedeo code to `PHP` — Tomero Indonesia, May 05 '14 at 10:15
It was the winner of a NIST competition, that's all I need to know really :) — Ja͢ck, May 05 '14 at 10:26

There is an official website of Keccak, which describes the alrgorithm in detail. It also explains and discusses the official code implementation.

Someone took the time to implement a few Keccak implementations into PHP, worth a look:
