Alley-OOP! ... or not?

Hey all, I've seen quite a few programs that seem to greatly favor Object Orienting Programming (OOP) in their code. I don't mean to start a holy war or anything of the sort, but as a burgeoning PHP developer, I would like the opinions of my peers. So how about it, ladies and gents? Tell me about the Pros and Cons to OOP, and why you prefer to use it/not use it! Personally, I've always used regular functions to accomplish my repetetive tasks, and OOP seems rather daunting for me, but I'm always open to new (and hopefully, more efficient) ideas! Thanks!
