I guess I wouldn't entirely switch from PHP to RoR, perhaps just adding Rails as an extra skill to my resume might do some good for me like someone else pointed out, more skills equals more opportunities. You're right about the ubiquity of PHP meaning someone else has written a library or script for doing almost anything I guess that's the plus of PHP being easy which in turn fuels a community.
