I found it doesn't work with my pre projects, cuz I've been using a lot of static class.

For example:  self::bar=new db();  self::$bar->(There is no autocomplete).

And it doesn't autocomplete the static function for example:

     class Foo{

           static function Bar(){

           }

     }

       Foo::(there is no autocomplete either)

     and I can't autocomplete the static class F(no autocomplete)
