@array = (5,5,null);
$array = $array * $array;
# output 25
$array = 10;
# output 50
if you know your code, you know that second
output statement is false.
you must re-calculate the value in $array2 to
get the output to come out as '50'
does anyone know of a way to make $array2
update itself automatically?
i should warn you not to pop a blood vessel trying to
answer this for me ... i'm reasonably convinced that
i will simply update $array2 on every pass of the
but for interest's sake i'd like to know if i can do it
the way i'd like to.
