Practical PHP OOP Examples?

You are a long way after the OOP revolution.  OOP was the "next big thing" in programming in the 1990s.  That era is long over.  It's no longer the shiny object (pun intended) in the room and while it is still useful and used, the number of people using it and the number of people promoting it is tiny compared to what it used to be.  OOP is generally pretty slow but helps people to think differently about programs and organize them.  I rarely do OOP today.  I'm a deeply trained OOP programmer and it has a lot of value.  But the "everything should be objects" era is over.
