On the Ibuildings blog today they've released the latest episode of their DPC Radio podcast series as recorded at this year's Dutch PHP Conference (2012). In this new episode, they share Boy Baukema's session "Let's Build a Parser".

During this talk an introduction will be given to parsing. Terms like 'formal grammar', 'lexing / scanning', 'LL / LALR / PEG' will be explained and put into context. We will look at a recursive descent parsing as a practical way to parse languages. Finally the audience will be left with ways to get started with parsing structured text into memory.

You can listen to this latest episode either through the in-page player or by downloading the mp3. You can also see the slides from the presentation on Slideshare.
