After working on Turm for a while, I collected enough experiences to judge PHP from my subjective point of view. Conclusion: PHP is not recommended. Neither as a web framework neither as scripting language. (details) As it seems PHP gained it’s popularity in historic moments. It is suitable to get things done quick and dirty, but it fails when it comes to a large project where it has to be a stable building block. Turm will be re-implemented in Ruby, .. will take some time tho.
