诡异事件，数组有关问题

$list=Array(    [page] => Array        (            [page_id] => 1,            [path] => tiyee.html,            [templates] => zj001.tpl,            [key] => 21212121,        ),    [qianggou] => Array        (            [object_id] => 1,            [number] => 0,            [oldprice] => 0.00,            [newprice] => 0.00,            [begintime] => 0000-00-00 00:00:00,            [endtime] => 0000-00-00 00:00:00,            [limit_b] => 0000-00-00 00:00:00,            [limit_e] => 0000-00-00 00:00:00,            [type] => 1,            [saleout] => 0,            [classtime] => 0000-00-00 00:00:00,            [page_id] => 1,        ),    [miaosha] => Array        (            [object_id] => 2,            [number] => 0,            [oldprice] => 0.00,            [newprice] => 0.00,            [begintime] => 2010-04-18 23:42:10,            [endtime] => 2010-04-18 23:42:10,            [limit_b] => 2010-04-18 23:42:10,            [limit_e] => 2010-04-18 23:42:10,            [type] => 2,            [saleout] => 0,            [classtime] => 0000-00-00 00:00:00,            [page_id] => 1,        ))echo '<pre>';print_r($list['page']);
