Object oriented??

I'm curious how the OOP features are viewed in PHP. I'm originally a C++ guy, and took to PHP because of the similarity. In C++ one wouldn't think of not using OOP principles, but frankly I cannot really figure out why one would go to OOP methods in PHP. It's not a true OOP implementation, though for web stuff it's probably close enough. I've written nothing but traditional code in PHP and like it that way. How common is this? Do most people write OOP or traditional linear code in PHP? Mike
