[RESOLVED] dynamic array

[[email protected]]

i have values stored in an array with key

 $array['total']['2001-11-09'];

the year month and day are as separate variables, how can i print its content out. I tried all below

$temp = $year."-".$month."-".$day;

echo $array['total'][$temp];
echo $array['total'][."'".$temp."'"];

none work.
