PhpStorm 2020.1 Help

Change Signature dialog

Refactor | Change Signature

The Change Signature refactoring combines several different modifications that can be applied to a method signature. You can use this refactoring to:

  • change the method name and return type

  • add, remove, and reorder parameters

  • assign default values to the parameters

  • change parameter names and types

  • propagate new parameters through the method call hierarchy

When changing a method signature, PhpStorm searches for all usages of the method and updates all the calls, implementations, and override replacements of the method that can be safely modified to reflect the change.

The Change Signature refactoring is supported only for PHP and JavaScript (see Refactoring JavaScript).
