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！
