PHP像基于重复密钥的数组一样组合VALUE而不仅仅是密钥本身

Question

我有一个如下所示的数组（这是一个$data变量的打印）

Array
(
    [0] => Array
        (
            [quan] => 1
            [prod_key] => 6f2e8858b8333afaeec8cd51be30ba6a
            [title] => Broomhandle - 6" x 12.5"
            [total] => 11.00
            [weight] => 0.25
            [image] => thumb_37658989fcd29e9.jpg
        )

    [1] => Array
        (
            [quan] => 1
            [prod_key] => 6f2e8858b8333afaeec8cd51be30ba6a
            [title] => Broomhandle - 6" x 12.5"
            [total] => 11.00
            [weight] => 0.25
            [image] => thumb_37658989fcd29e9.jpg
        )
    [2] => Array
        (
            [quan] => 1
            [prod_key] => of2ef85vb8333afaeec8cd51be30jq7i
            [title] => Watch
            [total] => 65.00
            [weight] => 0.15
            [image] => thumb_37658989fcd29e9.jpg
        )
)

我想做的是在数组中循环，将具有相同prod_键的项目组合成一个项目，并更新总数、数量和重量，这样上面的示例应该如下所示：

Array
(
    [0] => Array
        (
            [quan] => 2
            [prod_key] => 6f2e8858b8333afaeec8cd51be30ba6a
            [title] => Broomhandle - 6" x 12.5"
            [total] => 22.00
            [weight] => 0.50
            [image] => thumb_37658989fcd29e9.jpg
        )
    [1] => Array
        (
            [quan] => 1
            [prod_key] => of2ef85vb8333afaeec8cd51be30jq7i
            [title] => Watch
            [total] => 65.00
            [weight] => 0.15
            [image] => thumb_37658989fcd29e9.jpg
        )
)

Answer 1

创建一个新数组，并将产品密钥用作数组指示符。然后您可以轻松添加或更新条目

$result = array();
foreach ($data as $v) {
    if (!isset($result[$v['prod_key']])) {
        $result[$v['prod_key']] = $v;
    } else {
    $result[$v['prod_key']]['quan'] += $v['quan'];
    $result[$v['prod_key']]['total'] += $v['total'];
    $result[$v['prod_key']]['weight'] += $v['weight'];
        //etc...
    }
}
