You seem to be confusing two different things (in short, ?-> vs ->?):

  1. In PHP *too* we *already* have "*nullsafe* property access"
$objectThatMayBeNull?->property (but no "nullsafe array access"
$arrayThatMayBeNull?['key'], see
https://wiki.php.net/rfc/nullsafe_operator#future_scope) since PHP 8.0 (see
https://www.php.net/manual/en/migration80.new-features.php etc.)
  2. What may be proposed (in another RFC) is something like
$object->?propertyThatMayNotExist and/or $array[?'keyThatMayNotExist']
(call it e.g. "*lenient* property/array access"?) (JS is lenient by default)

But let's not deviate further.
