This class, trait or interface has been deprecated. The supplier of the file has supplied an explanatory message. The explanatory message should give you some clue as to whether and when the type will be removed from the class and what other constant to use instead. Loading history...

			0 ignored issues – show Bug Best Practice introduced 2017-11-15 09:22 UTC by Report Bug Copy Issue Report The expression `$methods` of type `array` is implicitly converted to a boolean; are you sure this is intended? If so, consider using `empty($expr)` instead to make it clear that you intend to check for an array without elements. This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent. Consider making the comparison explicit by using `empty(..)` or `! empty(...)` instead. Loading history...
