a) PHP has multiple platform support (ie. Windows, OSX, FreeBSD, Linux) so you can more easily transition when necessary and
b) the OS licenses required when you scale out horizontally are cheap (free!) for Linux, FreeBSD, which are the de-facto PHP platforms. (ie. think multiple database servers with multiple web servers with multiple load balancers, etc.)
Assuming you see yourself succeeding with your projects, always think 2 or 3 years down the road to what your system uptime & maintenance costs are going to be.
As an aside - when it comes to hiring developers, I'm guessing that PHP developers are cheaper and more plentiful as well.
