Unused declaration

Reports classes, methods, functions, constants, and properties that are either not used or unreachable from entry points. Also reports method implementations and overriders that are never called.

The inspection has two configuration options:

• Members to Report — select which element types are reported, and set the minimum visibility level (public, protected, or private) for methods, fields, and constants.

• Entry Points — configure what counts as used for a declaration:

  • Code patterns: add name patterns (glob/regex) whose matching declarations are treated as entry points.

  • Suppressed annotations: add custom PHPDoc annotations that suppress the warning.

  • Suppress getters and setters: select the checkbox to skip methods whose names start with get or set.

  • Suppress test entries: select the checkbox to treat test classes and methods as entry points (enabled by default).

  • Show only unused: select to also report members that are reachable from entry points but never called directly from outside the class. The default is Show all declarations.

Some unused members might not be reported in the code editor on the fly. Due to performance reasons, a non-private member is checked only when its name rarely occurs in the project.

To see all results, run the inspection in batch mode by using Code | Inspect Code... or Code | Run Inspection by Name....
