| Expand method bodies in completion for overrides | By default, when you want to override a method from the parent class or interface and select this method from the list of completion suggestions, PhpStorm automatically adds parameters, generates a Clear the Expand method bodies in completion for overrides checkbox to suppress automatic generation of method bodies for overrides during completion. |
