Hi, I'm an advanced designer, but also starting out a career in development: I'm a PHP intermediate user. I (unfortunately) learnt procedural development, and not OOP.
My current project is a multi-user game web-app and I was developing procedurally only for my Boss to insist that it has to be OOP, so I needed to start learning OOP (I believe I am a relatively fast learner). A friend advised me to just learn a lightweight PHP framework and move on from there, since the project must be launched in less than three weeks (I have roughly 2 weeks left now)!
After viewing a lot of articles comparing them, I ended up with CodeIgniter, Kohana, and Yii based on the efficiency and the lightweight-edness. I am not quite used to command-line instructions like it's done in Yii, so I had to drop it off to save my time :(. Kohana looks very interesting, but I am new to the PHP5 and OOP it uses and there's VERY LITTLE help on Kohana, I even tried to buy books but there are none. CodeIgniter has a lot of helpful material, but it has no official Authentication module with Access Control, and the three open-source modules I have tested did not integrate well with other modules I am using.
Please can anyone recommend another OOP PHP framework with a quick learning curve, or provide some pointers to resolve the problems I had with those 3 frameworks tested, or should I just develop the entire application out of the box after studying OOP extensively? Thanks for your time.
