在php中合并具有重复值的多维数组
在php中合并具有重复值的多维数组
提问于 2018-12-07 03:16:09
正如您所看到的，我有一个具有重复orderid的数组，因为一个订单可以有多个stockitems(stockitemname)。我如何合并数组，以便总计字段被求和，orderId不再重复，并且所有的orderId名都放在同一个orderId下？
有没有人有办法解决这个问题？
Array ( [0] => Array
([orderId] => 1544100294
[total] => 215.28
[receivedate] => 0000-00-00
[stockitemname] => "The Gu" red shirt XML tag t-shirt (White) XXS
[customerid] => 10 )
[1] => Array
( [orderId] => 1544119651
[total] => 37.38
[receivedate] => 0000-00-00
[stockitemname] => USB rocket launcher (Gray)
[customerid] => 10 )
[2] => Array
( [orderId] => 1544100294
[total] => 1614.60
[receivedate] => 0000-00-00
[stockitemname] => Large sized bubblewrap roll 50m
[customerid] => 10 ) )该数组是根据以下查询的结果创建的：
SELECT oc.orderId, SUM(so.quantity*si.RecommendedRetailPrice) total, oc.receivedate, si.stockitemname, ru.customerid
FROM orderbycustomers oc
JOIN registered_users ru
ON oc.customerid = ru.customerid
JOIN stockitemorders so
ON oc.orderId = so.orderId
JOIN stockitems si
ON so.StockItemID = si.StockItemID
WHERE oc.customerid = $customerid
GROUP BY si.stockitemname
ORDER BY oc.receivedate回答 1

另一种方法是在unique array中使用相同的id获取stockitems。
<?php
$input = Array ( Array
('orderId' => '1544100294',
'total' => 215.28,
'receivedate' => '0000-00-00',
'stockitemname' => 'The Gu red shirt XML tag t-shirt (White) XXS',
'customerid' => 10 ),
Array
( 'orderId' => '1544119651',
'total' => 37.38,
'receivedate' => '0000-00-00',
'stockitemname' => 'USB rocket launcher (Gray)',
'customerid' => 10 ),
Array
( 'orderId' => '1544100294',
'total' => 1614.60,
'receivedate' => '0000-00-00',
'stockitemname' => 'Large sized bubblewrap roll 50m',
'customerid' => 10 ) );
// New array using orderId as the key
$output = array();
foreach ($input as $values) {
// Define your key
$key = $values['orderId'];
// Assign to the new array using all of the actual values
$output[$key][] = $values;
}
// Get all values inside the array, but without orderId in the keys:
$output = array_values($output);
// Print the new array
print_r($output);
?>Here你可以看到它是如何工作的！
