PhpStorm 2020.1 Help

Code Inspection: Undefined callback

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

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.
