数组针对某项的求和问题
已知数组a:

<br />
array (<br />
  0 => <br />
  array (<br />
    'stock_no' => 'SU13080800340',<br />
    'adress' => 'B',<br />
    'arr_time' => '2013-08-14 09:00:00',<br />
    'c_type' => 'P32E',<br />
    'cust_no' => '310F61VA5A',<br />
    'mount_total' => '1',<br />
    'total' => '16',<br />
    'c1_time' => '2013-08-10 15:00:00',<br />
    'packageno' => 'CVT121015001',<br />
  ),<br />
  1 => <br />
  array (<br />
    'stock_no' => 'SU13080800340',<br />
    'adress' => 'B',<br />
    'arr_time' => '2013-08-14 09:00:00',<br />
    'c_type' => 'P32E',<br />
    'cust_no' => '310F61VA5B',<br />
    'mount_total' => '2',<br />
    'total' => '32',<br />
    'c1_time' => '2013-08-10 15:00:00',<br />
    'packageno' => 'CVT121015002',<br />
  ),<br />
  2 => <br />
  array (<br />
    'stock_no' => 'SU13080800340',<br />
    'adress' => 'B',<br />
    'arr_time' => '2013-08-14 09:00:00',<br />
    'c_type' => 'P32E',<br />
    'cust_no' => '310F61VA5B',<br />
    'mount_total' => '2',<br />
    'total' => '32',<br />
    'c1_time' => '2013-08-10 15:00:00',<br />
    'packageno' => 'CVT121226001',<br />
  ),<br />
)<br />


如何分别求得数组中的项cust_no对应的packageno的结果以及stock_no对应mount_total和total项求和的结果?
假设cust_no为310F61VA5A时,对应的packageno为CVT121225001。
    cust_no为310F61VA5B时,对应的packageno为CVT121225002,CVT121226001。

stock_no为SU13080800340时,求得的mount_total结果为3(1+2),total结果为48(16+32)。

如何达到这样的效果?
