For example, Which are the default defined constants in PHP?
This has been closed as NARQ, which is probably the best fit, but this is not true of that question.
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.
It is easy to tell what the OP wanted, and (IMO) it is not ambiguous, vague or any other adjective from the description.
The question could also be described as "Not Constructive", because it isn't, but again the reasons for it's non-constructiveness are not described by the description for NC.
The reason the question has been closed is because (like so many questions) the OP did not bother to do 30 seconds of research before asking a question.
I think there should be a close reason of "Lazy Question" or something similar, or the description of NARQ should be updated to include this kind of situation.
