数组加减问题
已知数组a和b。

<br />
//数组a:<br />
array (<br />
  0 => <br />
  array (<br />
    'cust_no' => '310F6 1VA5A',<br />
    'lotno' => '2X15',<br />
    'part_count' => '32',<br />
  ),<br />
  1 => <br />
  array (<br />
    'cust_no' => '310F6 1VA5A',<br />
    'lotno' => '2Z25',<br />
    'part_count' => '32',<br />
  ),<br />
)<br />
<br />
//数组b:<br />
<br />
array (<br />
  0 => <br />
  array (<br />
    'cust_no' => '310F6 1VA5A',<br />
    'total' => '48',<br />
  ),<br />
)<br />


数组a cust_no为310F6 1VA5A时,对应的总量是32+32=64,数组b cust_no为310F6 1VA5A时对应的总量是48。
想求得数组b总量为48时,对应数组a中的哪些内容?数组a剩余的结果是多少?

以这个例子来说,
得到数组a的结果:
<br />
//数组a:<br />
array (<br />
  0 => <br />
  array (<br />
    'cust_no' => '310F6 1VA5A',<br />
    'lotno' => '2X15',<br />
    'part_count' => '32',<br />
  ),<br />
  1 => <br />
  array (<br />
    'cust_no' => '310F6 1VA5A',<br />
    'lotno' => '2Z25',<br />
    'part_count' => '16',<br />
  ),<br />
)<br />

剩余数组a的结果:
<br />
//数组a:<br />
array (<br />
  0 => <br />
  array (<br />
    'cust_no' => '310F6 1VA5A',<br />
    'lotno' => '2X15',<br />
    'part_count' => '0',<br />
  ),<br />
  1 => <br />
  array (<br />
    'cust_no' => '310F6 1VA5A',<br />
    'lotno' => '2Z25',<br />
    'part_count' => '16',<br />
  ),<br />
)<br />


如何能得到这样的结果?
