如何从一个数组里拆出一部分作为一个新数组。
Array
(
  [totalcount] => 2
  [errorcount] => 0
  [orderlist] => Array
  (
  [order] => Array
  (
  [0] => Array
(
[orderamount] => 130.0
[ordercode] => 11111009FTHT
[ordercreatetime] => 2011-11-11 20:44:32
[orderdeliveryfee] => 0.0
[orderid] => 21919876
[orderneedinvoice] => 0
[orderstatus] => ORDER_OUT_OF_WH
[productamount] => 130.0
)

[1] => Array
(
[orderamount] => 200.0
[ordercode] => 3311009FTHT
[ordercreatetime] => 2011-05-11 20:44:32
[orderdeliveryfee] => 0.0
[orderid] => 21919876
[orderneedinvoice] => 0
[orderstatus] => ORDER_OUT_OF_dfd
[productamount] => 130.0
)

  )

  )

  [encoding] => UTF-8
)




这个数组 我需要[order] 里面的部分 提出来作为一个新数组, 怎么处理呢。

------解决方案--------------------
$new_arr = $all_arr['order'];
------解决方案--------------------
假设$arr为你的原数组.
$NewArr=$arr['order'];
------解决方案--------------------
楼上两位没看清楚数组结构吧:

PHP code

//对需要的数组进行修改
$newArr=$arr['orderlist']['order'];

//如果需要将修改的结果合并回原数组:
$arr['orderlist']['order']=$newArr; <div class="clear">
                 
              
              
        
            </div>
Copy after login
