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...

			0 ignored issues – show Bug introduced 2017-01-02 12:44 UTC by Report Bug Copy Issue Report Are you sure the assignment to `$blockExit` is correct as `$block->getExit()` (which targets `PHPSA\ControlFlow\Block::getExit()`) seems to always return null. This check looks for function or method calls that always return null and whose return value is assigned to a variable. class A { function getObject() { return null; } } $a = new A(); $object = $a->getObject(); The method `getObject()` can return nothing but null, so it makes no sense to assign that value to a variable. The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. Loading history...

A high number of execution paths generally suggests many nested conditional statements and make the code less readible. This can usually be fixed by splitting the method into several smaller methods.
