This check looks at variables that have been passed in as parameters and are passed out again to other methods. If the outgoing method call has stricter type requirements than the method itself, an issue is raised. An additional type check may prevent trouble. Loading history...

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.
