I just finished reading book "PHP Team Development"
and I can say its interesting read, especially should be interesting for project managers. It might look that there are not many technical things and its waste of time on one hand, but its easy read when you are not in the mood of thinking about dificult code.
Also many things there might be already self-evident, but its good to know that professionals think the same way, for exaple that programer is a human and has its own life, that he has to be happy and so on.
While for me it looks that little amount of companies think much about such things like worker happiness. They just want the work done and pay as little as posible.
