Before $a = &$value
is evaluated, the local $a
and the global $a
reference the same value (null
). After that reference assignment, the local $a
and the local $value
reference the same value (1
). As such, the local $a
looses the reference to the value null
. That does not happen with $c
, because you're not assigning by-ref.
