Hello! PHP currently supports ??= assignment, as shortly to $a = $a ?? null, but it does not supports ?:= as shortly to $a = $a ?: null.
There are some reason to that? - https://wiki.php.net/rfc/null_coalesce_equal_operator - https://wiki.php.net/rfc/short_ternary_equal_operator Thanks! Atenciosamente, David Rodrigues
