将已知数组按条件分为若个新数组

已知数组:
array (  0 =>   array (    'po_num' => 'DYNP-770266110-00',    'plant' => 'DYNP',    'get_date' => '2013-09-09',    'cust_no' => '12654172',    'total' => '615',    'snp' => '15',    'mount' => '41',    'lp_no' => 'P000000D',  ),  1 =>   array (    'po_num' => 'DYNP-770266110-00',    'plant' => 'DYNP',    'get_date' => '2013-09-09',    'cust_no' => '12647212',    'total' => '60',    'snp' => '15',    'mount' => '4',    'lp_no' => 'P000000D',  ),)


能否按字段total为100为单位把数组再分为若干个新的数组?并加上序号字段在其中,比如:
  array (    'po_num' => '1/7',//新增字段信息    'po_num' => 'DYNP-770266110-00',    'plant' => 'DYNP',    'get_date' => '2013-09-09',    'cust_no' => '12654172',    'total' => '615',    'snp' => '15',    'mount' => '41',    'lp_no' => 'P000000D',  ),...)

是啊。又是这种问题。
[6] => Array
(
[po_no] => 7/7
[po_num] => DYNP-770266110-00
[plant] => DYNP
[get_date] => 2013-09-09
[cust_no] => 12654172
[total] => 15
)

[7] => Array
(
[po_num] => DYNP-770266110-00
[plant] => DYNP
[get_date] => 2013-09-09
[cust_no] => 12647212
[total] => 60
)

这个能不能作为一项来处理?将原来的数组并到前一个数组中,而不是重新计算$i/$n的序列号。变成这样的形式:

[6] => Array
(
[po_no] => 7/7
[po_num] => DYNP-770266110-00
[plant] => DYNP
[get_date] => 2013-09-09
[cust_no] => 12654172
[total] => 15
)

[7] => Array
(
[po_no] => 7/7
[po_num] => DYNP-770266110-00
[plant] => DYNP
[get_date] => 2013-09-09
[cust_no] => 12647212
[total] => 60 //15+60=75 )

又来了?

不好意思,发现问过这个问题了,抱歉!
