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
