问题
I recently downloaded PhpStorm 5. Everything work fine with verion 4, but now I can not access to native php functions on autocomplete. Functions and classes declared in my project are still there. Any ideas ?

Try File | Invalidate Caches, also check that PHP interpreter is configured for the project (File | Settings | PHP, Interpreter).
