$arr = [
'6d7470ef' =>[
'shop_id'=>'1',
'total'=>'30',
'num'=>'1',
],
'd2f87737' =>[
'shop_id'=>'1',
'total'=>'60',
'num'=>'2',
],
'255211b6' =>[
'shop_id'=>'2',
'total'=>'30',
'num'=>'1',
],
'1d707990' =>[
'shop_id'=>'2',
'total'=>'90',
'num'=>'3',
],
];
$a = [];
foreach($arr as $k=>$vo){
$a[$vo['shop_id']][] = $vo;
$a[$vo['shop_id']]['shopnum'] += $vo['num'];
}
echo '<pre>';
print_r($a);代码如上，在tp5框架里操作提示错误未定义数组索引: shopnum
不使用框架执行没有问题
