Why do nearly all php-related e-commerce websites use object-oriented programming as a basic foundation?
I was just looking through many books about php e-commerce websites (like [Beginning PHP and MySQL E-Commerce][1]) and I realised that so many use object-oriented programming as a basic foundation. I thought about it, and I realised it is perfectly possible to replicate those e-commerce websites without using object-oriented programming, so why do they all go for OOP?

Thanks,

Lucas
