第一项OK,但是mount_total和total的求和结果不对,我要的是stock_no为SU13080800340时,求得的mount_total结果为3(1+2),total结果为48(16+32)。
$res = array();foreach($a as $item) { if(! isset($res[$item['stock_no']][$item['cust_no']])) { $res[$item['stock_no']][$item['cust_no']] = $item; }else { $res[$item['stock_no']][$item['cust_no']]['mount_total'] += $item['mount_total']; $res[$item['stock_no']][$item['cust_no']]['total'] += $item['total']; $res[$item['stock_no']][$item['cust_no']]['packageno'] .= ',' .$item['packageno']; }}foreach($res as &$item) $item = array_values($item);print_r($res);
楼主这种问题 应该算是比较基础的 我有点好奇为什么会纠结于
Array
(
[0] => 16
[1] => 32
[2] => 32
)
这种数组的加和? 你的需求应该是去了重复求和.... 一个PHP函数的事情...
你的数组中三个stock_no的值不是一样的吗,都为 SU13080800340 吧,难道我眼花了?
那是你的数据给错了
'cust_no' => '310F61VA5A',
'mount_total' => '1',
'total' => '16',
'cust_no' => '310F61VA5B',
'mount_total' => '2',
'total' => '32',
'cust_no' => '310F61VA5B',
'mount_total' => '2',
'total' => '32',
那是你的数据给错了
'cust_no' => '310F61VA5A',
'mount_total' => '1',
'total' => '16',
'cust_no' => '310F61VA5B',
'mount_total' => '2',
'total' => '32',
'cust_no' => '310F61VA5B',
'mount_total' => '2',
'total' => '32',
那我再想想。
你的数组中三个stock_no的值不是一样的吗,都为 SU13080800340 吧,难道我眼花了?
那怎么去重复求和呢?
データが間違っているためです
'cust_no' => '310F61VA5A',
'mount_total' => '16',
= > '310F61VA5B',
'mount_total' => '2'、
'total' => '310F61VA5B'、
'mount_total' = > 'total' => '32'、
合計を繰り返したい場合はどうすればよいでしょうか?
それはあなたのデータが間違っているからです
'cust_no' => '310F61VA5A',
'mount_total' => '16',
'mount_total' => '2'、
'total' => '310F61VA5B'、
'mount_total' =>
'total' => '32',
合計を繰り返したい場合はどうすればよいでしょうか?
和を繰り返して1階を見上げると....
