Refactoringaction: net.sourceforge.phpdt.ltk.ui.actions.RenameLocalVariable
This refactoring replaces any $-variable inside a function or method declaration
The action can detect the scope of a PHP function or class method.
NEW: this refactoring now replaces variables inside double quoted strings.

This refactoring doesn't look for global variables inside the function or method.
This refactoring doesn't look correctly for "self::" and "$this" tokens inside the function or method.
This refactoring doesn't look for a preceding PHPDoc comment and therefore cannot replace any local variables inside the PHPdoc comment.
