Scalable and flexible framework for e commerce website based on PHP or Django

I have to build an e commerce website that aims to target very heavy traffic 2 to 3 years down the lane. I am comfortable with PHP or Python.

I would like to know what would be the best framework that I should use? Which solution would off开发者_如何学Cer the scalability and ease of development? Moreover I would like the framework to be totally customizable. I have looked at various frameworks such as Magneto, OpenCart, PrestaShop, zen cart and loads of more. But frankly I can't understand well enough any of them until I dwell into the development.

But I cannot afford to waste time by experimenting with these solutions. I would like to know whether I should go for any framework at all?

Any help is really appreciated.

If you need a Django based E commerce site, I would suggest Satchmo Project:

Do you need a customized shopping cart or eccommerce application built with Python?

Do you need to add a Django based shopping cart to an existing site?
