function equals() does not seem to conform to the naming convention (^(?:is|has|should|may|supports)).
This check examines a number of code elements and verifies that they conform
to the given naming conventions.
You can set conventions for local variables, abstract classes, utility classes, constant, properties,
methods, parameters, interfaces, classes, exceptions and special methods.
This check looks for the generic type
array
as a return type and suggests a more specific type. This type is inferred from the actual code.
