PHP：如何索引多个嵌套数组的列表？

Question

我怎么能指数低于阵列，

array 
(
    [1403847357564066] => Array 
     (
      [quantity_request] => 1 
      [time_created] => 1339603485 
      [variant] => Array 
       (
       ) 
     ) 

    [1403873546800880] => Array 
     (
      [quantity_request] => 1 
      [time_created] => 1339602425 
      [variant] => Array 
       (
       ) 

     ) 

) 

或者我可以得到，

array(
[0] => array(
     [1403847357564066] => Array 
       (
        [quantity_request] => 1 
        [time_created] => 1339609120 
        [variant] => Array 
         (
         ) 

       ) 
     ), 
[1] => array(

      [1403847343435137] => Array 
       (
        [quantity_request] => 1 
        [time_created] => 1339609500 
        [variant] => Array 
         (
         ) 

       ) 
     )

$newarray=array(); 
foreach ($oldarray as $k=>$v) $newarray[]=array($k=>$v);
