PHP通过值删除数组索引

Question

我正在尝试取消设置包含两个值的两个特定数组位置。

我填充数组的实际代码。

function get_store_list(){
    $data = @file_get_contents('http://www.zwinky.com/xml/clothingList.xml');
    $data = @simplexml_load_string($data);
    $data = $data->xpath('//stores/store');

    foreach($data as $store) {
        $storeArray[] = array(
           "name" => (string)$store['name'],
           "id"   => (string)$store['id']
        );
     }

    return $storeArray;
}

$store = get_store_list();

数组看起来像下面这样，以防万一使用 print_r 函数将其回显:

Array
(
[0] => Array
    (
        [name] => Artizans
        [id] => 20037336
    )

    (
        [name] => Bwabies!

        [name] => The Castle
        [id] => 1
    )

[17] => Array
    (
        [name] => The Lair
        [id] => 4
    )

        [name] => The Mix

    (
        [name] => The Surf Shop
        [id] => 5
    )

    (
        [name] => Tie The Knot
        [id] => 20076231
    )

[22] => Array
    (
        [name] => tokidoki
        [id] => 20099224
    )

[23] => Array
    (
        [name] => University Club
        [id] => 2
    )

[24] => Array
    (
        [name] => Z Avenue
        [id] => 6
    )

[25] => Array
    (
        [name] => Z's Greetings
        [id] => 20099506
    )
)

现在 $store 确实包含 2 个我必须删除的数组索引。以下是哪些 id:21 和 20076231

我已经尝试过以下方法:

Array search code没有成功。有谁知道我可以尝试什么？

对于这个简单的问题，有几种不同的方法。其中之一可能是使用函数 array_filter() :

/**
 * @param array $list        the list to process
 * @param array $IDsToRemove the IDs of elements to remove from $list
 * @return array a subset of $list that does not contain elements having 'id' in $IDsToRemove
 */
function removeFromArray(array $list, array $IDsToRemove)
{
    return array_filter(
        // Filter the input list...
        $list,
        // ... using a function...
        function (array $item) use ($IDsToRemove) {
            // ... that accepts an element if its "id" is not in $IDsToRemove
            return ! in_array($item['id'], $IDsToRemove);
        }
    );
}

// Usage
$filteredStore = removeFromArray($store, array(21, 20076231));
