Does anyone know if this is a philodendron,or what else it is?

That is not a philodendron. It looks more like a bay to me, and closer to an outdoor 'hedge' such as the ones that many people have in their yards. You didn't put anything next to the leaves, though, to give us an idea as to the size of them, so I suggest you do a search using the words 'bay hedge' or 'bay leaf plants' and find a good source that lists all of them with images. Good luck!
