If PHP is your choice and not the result of prior mismanagement, then I would immediately schedule a two-week vacation. Rent a suite at a hotel with no internet service. Bring your laptop. Pick a language: Scheme, Groovy, Python, Ruby, Clojure, scala, Haskell... and implement something fun for twelve days. Do nothing but immerse yourself in the language. Take a couple days of rest. Then return to work freed of the huge mistake that is PHP.
