Ah ok, gotcha. As I have to maintain a few legacy PHP servers.. I would strongly recommend you take a look at NGINX + PHP-FPM replacing Apache too so you can simplify the stack a bit.
NGINX is pretty awesome as a reverse proxy (as you must know) but its very nice when you use it as your web server too.
