内容图文
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', ),...）

需求不明确~~
又来了？
$ar = array ( 0 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12654172', 'total' => '615', 'snp' => '15', 'mount' => '41', 'lp_no' => 'P000000D', ), 1 => array ( 'po_num' => 'DYNP-770266110-00', 'plant' => 'DYNP', 'get_date' => '2013-09-09', 'cust_no' => '12647212', 'total' => '60', 'snp' => '15', 'mount' => '4', 'lp_no' => 'P000000D', ),);$split_num = 100;foreach($ar as $item) { if($item['total'] <= $split_num) { $res[] = $item; continue; } $total = $item['total']; $n = ceil($total/$split_num); for($i=1; $i<$n; $i++) { $res[] = array_merge(array('po_nume' => "$i/$n"), $item, array('total' => $split_num)); } $res[] = array_merge(array('po_nume' => "$i/$n"), $item, array('total' => $total%$split_num));}print_r($res); Array( [0] => Array ( [po_nume] => 1/7 [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12654172 [total] => 100 [snp] => 15 [mount] => 41 [lp_no] => P000000D ) [1] => Array ( [po_nume] => 2/7 [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12654172 [total] => 100 [snp] => 15 [mount] => 41 [lp_no] => P000000D ) [2] => Array ( [po_nume] => 3/7 [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12654172 [total] => 100 [snp] => 15 [mount] => 41 [lp_no] => P000000D ) [3] => Array ( [po_nume] => 4/7 [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12654172 [total] => 100 [snp] => 15 [mount] => 41 [lp_no] => P000000D ) [4] => Array ( [po_nume] => 5/7 [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12654172 [total] => 100 [snp] => 15 [mount] => 41 [lp_no] => P000000D ) [5] => Array ( [po_nume] => 6/7 [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12654172 [total] => 100 [snp] => 15 [mount] => 41 [lp_no] => P000000D ) [6] => Array ( [po_nume] => 7/7 [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12654172 [total] => 15 [snp] => 15 [mount] => 41 [lp_no] => P000000D ) [7] => Array ( [po_num] => DYNP-770266110-00 [plant] => DYNP [get_date] => 2013-09-09 [cust_no] => 12647212 [total] => 60 [snp] => 15 [mount] => 4 [lp_no] => P000000D ))
...
是啊。又是这种问题。
[6] => Array
(
[po_no] => 7/7
[po_num] => DYNP-770266110-00
[plant] => DYNP
[get_date] => 2013-09-09
[cust_no] => 12654172
[total] => 15
)
[7] => Array
(
[po_num] => DYNP-770266110-00
[plant] => DYNP
[get_date] => 2013-09-09
[cust_no] => 12647212
[total] => 60
)
这个能不能作为一项来处理？将原来的数组并到前一个数组中，而不是重新计算$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 < 100
)
又来了？
不好意思，发现问过这个问题了，抱歉！
