Matthew Setter demonstrates PhpStorm's handy refactorings. Personally I use "extracting code to a new method" quite a lot.

Refactoring covers a range of different techniques, including moving, extracting, copying, deleting, and renaming. These cover all the types of changes which you are likely to make to your code on an ongoing basis.

  • Renaming a function
  • Changing a function's signature
