This check looks for function or method calls that always return null and whose return value is used.
class A { function getObject() { return null; } } $a = new A(); if ($a->getObject()) {
The method getObject() can return nothing but null, so it makes no sense to use the return value.
getObject()
The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes.
