        [7] => 80364
        [invoiceid] => 80364
    )

我需要在数组[quantity_consumed]的键相同的地方添加[INV828]。我想添加256 + 56的[quantity_consumed]值并将其设为1。< / p>

Answer 1

如果您有一个键值相同的关联数组（例如[INV828]），则最新条目将覆盖现有条目。

有关更多信息，请参见：PHP Manual Arrays

因此您的阵列将只有以下条目：

[INV828] => Array
(
    [0] => shams interior
    [org_name] => shams interior
    [1] => INV828
    [inv_no] => INV828
    [2] => 1556
    [productid] => 1556
    [3] => E001-4ft
    [productname] => E001-4ft
    [4] => Paharganj
    [warehousename] => Paharganj
    [5] => 2018-04-19 16:55:05
    [date] => 2018-04-19 16:55:05
    [6] => 56
    [quantity_consumed] => 56
    [7] => 80364
    [invoiceid] => 80364
)

Answer 2

尝试一下：-

$arr = array(
    array('org_name' => 'shams interior','inv_no' => 'INV828','productid' => 1556,'productname' => 'E001-4ft','warehousename' => 'Paharganj','date' => '2018-04-19 16:55:05','quantity_consumed' => 256,'invoiceid' => 80364),
    array('org_name' => 'shams interior','inv_no' => 'INV829','productid' => 1556,'productname' => 'E001-4ft','warehousename' => 'Paharganj','date' => '2018-04-19 16:55:05','quantity_consumed' => 256,'invoiceid' => 80364),
    array('org_name' => 'shams interior','inv_no' => 'INV828','productid' => 1556,'productname' => 'E001-4ft','warehousename' => 'Paharganj','date' => '2018-04-19 16:55:05','quantity_consumed' => 56,'invoiceid' => 80364),
    array('org_name' => 'shams interior','inv_no' => 'INV829','productid' => 1556,'productname' => 'E001-4ft','warehousename' => 'Paharganj','date' => '2018-04-19 16:55:05','quantity_consumed' => 256,'invoiceid' => 80364)
    );
$newArray = array();
foreach($arr as $k => $data) {
    if (array_key_exists($data['inv_no'], $newArray)) { // If inv_no key is already exists, then just add the consumed quantity
        $newArray[$data['inv_no']]['quantity_consumed'] = $newArray[$data['inv_no']]['quantity_consumed'] + $data['quantity_consumed'];
    } else { // else add the data as new inv_no key
        $newArray[$data['inv_no']] = $data;
    }
}
echo "<pre>";
print_r($newArray);

输出：-

Array
(
    [INV828] => Array
        (
            [org_name] => shams interior
            [inv_no] => INV828
            [productid] => 1556
            [productname] => E001-4ft
            [warehousename] => Paharganj
            [date] => 2018-04-19 16:55:05
            [quantity_consumed] => 312
            [invoiceid] => 80364
        )

    [INV829] => Array
        (
            [org_name] => shams interior
            [inv_no] => INV829
            [productid] => 1556
            [productname] => E001-4ft
            [warehousename] => Paharganj
            [date] => 2018-04-19 16:55:05
            [quantity_consumed] => 512
            [invoiceid] => 80364
        )

)

如果密钥相同，我将如何增加数量
