To itself, surely. I say for $N'th time - references are like Unix files,
they do *NOT* point to other variable, they point to variable
contents. Saying $a = &$b means "make a point to the same contents as b
does".
That does not matter. *If* we had a function that extracts that *virtual* information like print_r does we could serialize that information to.
No. There's no such thing as "reference points to variable", there is a
thing that "reference is an operation which makes two variables point to
the same content".
Despite that would not represent how references are preseneted technically it would allow serializing references.
