数组计算差值及项的小计,该如何处理
数组计算差值及项的小计
求其type对应的差值和$s[0]及$s[1]的type项的小计。（小计部分已实现，用了unset）
理想得到的结果：
小计的结果： BEA01-120N 176 BEA01-120N 192 差值：176-192 = -16
BEA21-110N 1056 BEA21-110N 960 1056-960 = 96
小计：176+1056=1232 192+960 = 1152

$s = array (
0 => array (
0 => array (
0 => '2014-04-11', 'time' => '2014-04-11',
1 => 'BEA01-120N', 'type' => 'BEA01-120N',
2 => 176, 'count' => 176,
),

Array小计你已经做了，我就偷懒了
(
[0] => Array
(
[0] => BEA01-120N
[1] => -16
)
[1] => Array
(
[0] => BEA21-110N
[1] => 96
)
)
