Ilia Alshanetsky has a quick post about two articles of relevance in the latest issue of php|architect - a PDO article and a review of FUDforum.

The BC break that was made recently. So if you are considering using PDO, this is definitely something that should be of interest.

The issue also held a pleasant surprise for me, which was a fairly detailed and positive this latest edition and it does give a good overview of what it is and how to use it. And FUDforum, well, that's just an outstanding piece of forum software anyway...
