It's not that everyone is copying Java, just that languages are adding more OOP features. Java wasn't the first language with OOP principles, though it is probably the most mature language designed entirely around OOP. PHP is including it because it's becoming a popular methodology. I think more people are becoming aware of the benefits of OOP, and it's nice to see that languages are accomodating that. In the end, it's just a different approach to doing the same thing.
