Undefined callback

Reports the functions, methods, properties, or classes that are referenced from a callback but are not found.

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

PhpUndefinedCallbackInspection
Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | PHP | Undefined symbols

Use the options below to customize the inspection:

  • Ignore callback from *_exists and is_callable functions: if selected, the inspection will skip callback references from the method_exists, function_exists, property_exists, class_exists and is_callable functions.

  • Don't report in case of ambiguity: if selected, the inspection will skip the parameters with multiple possible types, for example marked as callable|string.
