Question

我有一个如下所示的数组：

Array
(
    [333824-00A-BLK-10] => Array
        (
            [classId] => 44
            [inv] => 0.000
            [onOrder] => 0
            [code] => 333824-00A-BLK-10
        )
    [333824-00A-BLK-10.5] => Array
        (
            [classId] => 44
            [inv] => 0.000
            [onOrder] => 0
            [code] => 333824-00A-BLK-10.5
        )
)

我想使用另一个如下所示的数组来过滤它：

Array
(
    [0] => 333824-00A-BLK-10
    [1] => 333824-00A-BLK-10.5
    [2] => 333824-00A-BLK-11
    [3] => 333824-00A-BLK-11.5
    [4] => 333824-00A-BLK-12
)

我想将结果保留在数组中，并删除不匹配的键。我尝试过一个用foreach过滤数组但没有运气的函数。有什么帮助吗？谢谢！

Answer 1

$result = array_intersect_key($data, array_flip($keys));

$data是您的主数组，而$keys是一个包含要过滤的键的数组

Answer 2

我会做一个虚拟数组并在foreach中过滤它，我不知道你的foreach看起来如何，但我的看起来像

$arr = array();

$filter_array = array ('333824-00A-BLK-10',
     '333824-00A-BLK-10.5',
     '333824-00A-BLK-11',
    '333824-00A-BLK-11.5',
     '333824-00A-BLK-12');

$array_to_filter = array('333824-00A-BLK-10' => array
        (
            'classId' => 44,
            'inv' => 0.000,
            'onOrder' => 0,
            'code' => '333824-00A-BLK-10'
        ),
    '333824-00A-BLK-10.5' => array
        (
            'classId' => 44,
            'inv' => 0.000,
            'onOrder' => 0,
            'code' => '333824-00A-BLK-10.5'
        )
);

foreach($array_to_filter as $filter) {

    if(array_key_exists($filter, $array_to_filter)) {
        $arr[] = $array_to_filter[$filter];
    }
}

<$>在$ arr中，您现在应该拥有数组中的所有现有键

使用另一个数组php过滤数组
