I second the use of “void" over “null” - for what it's worth.
Mainly the rationale for me is that I would like to reserve “null” for empty or
non-existent object.
[
“key” => 1,
“key2” => null // empty object
]
“void" is already being used on the tail of functions to say, “This thing does
not return anything; and can be ignored.”
So:
foreach($collection as $key => void)
Says, “This thing can be ignored” (void) and not, “this thing doesn’t exist but
maybe should” (null).
Cheers,
