php - PhpStorm refactor local variable to class field -


like in topic, want refactor local variable class field.

i thinking of 2 approaches:

a. quick , simple:
want refactor name of variable $var $this->var.

b. extended version:

from: 

class x {     function y() {         $var = new targetclass;     } }

to:

class x {     /** @var targetclass $var */ // version c, optional     (public|protected|private) $var;     function y() {         $this->var = new targetclass;     } }

can't of this, when try refactor $var, refactoring $this->var, end message:

inserted identifier invalid

defining $this->var first doesn't either.

only workaround found type $this->var, loose focus on refactoring variable, type whatever , delete it. phpstorm cheated , variable changed. simple dirty-covers approach a.

select variable , rightclick. choose refactor->extract->field. enter name wan't field.
