Additional Information for References in Arrays

From manual page: https://php.net/language.references.whatdo

I think it would make a lot of sense to add the piece of information that references inside arrays are highlighted as such when using var_dump() with the array. I am talking about something like this:

array(4) {
  [0]=>
  int(0)
  [1]=>
  &int(1)
  [2]=>
  int(2)
  [3]=>
  int(3)
}

It seems that this piece of information is neither available in the chapter on references nor in the definition of var_dump():
https://www.php.net/manual/en/language.references.whatdo.php and https://www.php.net/manual/en/function.var-dump. I think it should be.

Start by reading the references and var_dump() manual pages linked in the issue, then compare their current explanations with the supplied output. Update the relevant PHP documentation to explain that references in arrays are highlighted by var_dump(), including a suitable example, and verify that both topics describe the behavior consistently.
