We've made the corporate decision - after many bad experiences - to purge PHP from production, for the sake of our sanity.
We are not doing this lightly. The current codebase has ~2.5 man years invested in it.

So in summary, I bet that purging PHP was tough, and I think you made the right choice.
Anyway, I truly wish you luck with you project, but I would advise not to drop any particular technology just for sake of dropping it.
