I don't see a problem in using PHP. Consider how you break down your infrastructure. Don't build monolithic code-bases which you cannot maintain. Make small compact services (SOA) which you know you can build out quickly. RoR is for people who want to spend a lot of time learning the framework. At this point, it's so large you will probably never even feel like you can encompass it's full size. Kinda like django. Don't ditch php because people say it doesn't scale. YouPorn.com thought it scaled quite well. They get a crap load of traffic to boot.
