There are now so many Frameworks out there for php (just have a short look at dmoz, there are 46 listed, missing some wellknown ones like ezComponents, ZendFramework, Solar, Symfony, Code Igniter, ..., and what about PEAR??) - but which one are you going to use? Well, i guess it is a challenging question, especially if it is now up to you to decide this for a new starting project. Probably all frameworks have some strengths and weaknesses, but how long does it take you to evaluate them? You need some faster criteria to decide, and maybe these one will help you.
The "must have" questions he shares include:
- Is the framework well documented?
- Is the framework backed by a well known company?
- Does the framework fit into your IT-landscape?
