PHP array_search通过变量在多维数组中

Question

我有一个数组，我想在其中过滤掉有关 OrderId 的所有信息。因此，我想通过一个包含我的 OrderId 的变量来数组搜索我的数组。 这样我就可以获取数组键，然后用array_slice对数组进行切片。

Array
( 
    [Order] => Array
        ( 
            [0] => Array
                ( 
                    [OrderId] => 4832413060 
                    [DateTimeCustomer] => 2018-07-17T12:55:07.000+02:00 
                    [DateTimeDropShipper] => 2018-07-17T12:55:07.000+02:00 
                    [CustomerDetails] => Array 
                        ( 
                            [ShipmentDetails] => Array 
                                ( 
                                    [SalutationCode] => 01 
                                    [Firstname] => name

                                )
                        )
                ) 
            [1] => Array

                                ( 
                                    [OrderItemId] => orderitemid 
                                    [OfferReference] => Array 
                                        ( 

                                        ) 
                                    [EAN] => ean 
                                    [Title] => title 
                                    [Quantity] => 1 
                                    [OfferPrice] => 14.95 
                                    [TransactionFee] => 3.24 
                                    [LatestDeliveryDate] => 2018-07-18+02:00 
                                )
                        )
                ) 

我试过的代码：

foreach ($items as $item) {
$key = array_search($item, $array1);

$item 与 OrderId 相同。

我尝试了许多来自互联网的不同示例，但不幸的是，似乎没有什么对我有用。

Answer 1

我认为您可以使用 array_column 使数组与 orderid 作为键关联，从而很容易找到 orderid。
但这假设您在数组中只有唯一的 orderid。

$find = 4832413060;
$arr = array_column($arr, NULL, 'orderid');

$findOrder = $arr[$find];

Var_dump($findOrder);

我做了一个小数组来演示代码。

Answer 2

array_search() 不适用于多维数组。使用array_filter()

foreach ($items as $item) {
    $found = array_filter($array, function($element) use($item) {
        return $element['OrderId'] == $item;
    }
    // $found now contains all the elements in the original array for $item
    ...
}
