Rapid application development – which framework to use?

Leave a reply

I always want to do a very fast application development. This can only be done with what we call a “framework”. I have been doing a lot of research on popular PHP framework but not yet decided which one to use.

Some of them are cakephp, codeigniter, symphony and rapyd.

After using it for some time will plan to come out with own framework for better control and easy modification on the code.
