php数组的有关问题

php数组的问题
我也不知道是什么问题，
我有个数组（从数据库中取出来的）
Array
(
[0] => 2
[testconment_id] => 2
[1] =>
[testconment_userid] =>
[2] => 2
[testconment_testid] => 2
[3] =>
[testconment_typeid] =>
[4] =>
[testconment_flag] =>
[5] => 你好啊啊啊啊
[testconment_content] => 你好啊啊啊啊
[6] => 2012-05-02 05:25:03
[testconment_date] => 2012-05-02 05:25:03
)

通过循环取值
foreach($commentList as $v){
$commentTemp["id"]=$v["testconment_id"];
$commentTemp["userid"]=$v["testconment_userid"];
$commentTemp["testid"]=$v["testconment_testid"];
$commentTemp["typeid"]=$v["testconment_typeid"];
$commentTemp["flag"]=$v["testconment_flag"];
$commentTemp["content"]=$v["testconment_content"];
$commentTemp["date"]=$v["testconment_date"];
array_push($commentArray,$commentTemp);
}
我将$commentArray打印出来
Array
(
[0] => Array
(
[id] => 2
[userid] => 2
[testid] => 2
[typeid] => 2
[flag] => 2
[content] => 2
[date] => 2
)

[1] => Array
(
[id] => 2
[userid] => 2
[testid] => 2
[typeid] => 2
[flag] => 2
[content] => 2
[date] => 2
)
