if you have the luxury you should learn something other than php. you likely won't find the transition to python too difficult. if you are already really productive in php; it probably isn't a huge priority. another thing to think about is looking at something like haskell/lisp/clojure which is probably more a difficult task to pick up; but will eventually (in theory, and if you can grok it) lead to even greater produtivity; probably not the route to go if you are looking for a job, but as an entrepreneur it is probably a really good use of time, if you've the luxury.
