			0 ignored issues – show Bug introduced 2018-01-11 00:34 UTC by Report Bug Copy Issue Report It seems like `$session` defined by parameter `$session` on line `196` can be `null`; however, `Sesshin\SessionFlash::__construct()` does not accept `null`, maybe add an additional type check? It seems like you allow that null is being passed for a parameter, however the function which is called does not seem to accept null. We recommend to add an additional type check (or disallow null for the parameter): function notNullable(stdClass $x) { } // Unsafe function withoutCheck(stdClass $x = null) { notNullable($x); } // Safe - Alternative 1: Adding Additional Type-Check function withCheck(stdClass $x = null) { if ($x instanceof stdClass) { notNullable($x); } } // Safe - Alternative 2: Changing Parameter function withNonNullableParam(stdClass $x) { notNullable($x); } Loading history...
