There are two topics I'd like to suggest as possible topic(s) for a next meetup concerning PHP. These would involve respectively;
1. A tutorial on the use of Namespaces in PHP, illustrated by examples from "real-life applications".
2. Techniques for Defensive Programming in PHP.
This last might be more suited for a debate kind of session, with the speaker acting more in the role of a catalyst or facilitator.
What do you think about these topics; would they interest you and might you be able to contribute or be willing to speak on them?
