		0 ignored issues – show Documentation Bug introduced 2016-05-19 13:20 UTC by Report Bug Copy Issue Report The property `$current` was declared of type `string`, but `false` is of type `false`. Maybe add a type cast? This check looks for assignments to scalar types that may be of the wrong type. To ensure the code behaves as expected, it may be a good idea to add an explicit type cast. $answer = 42; $correct = false; $correct = (bool) $answer; Loading history...
