Question

我有两个多维数组，我想根据第二个数组更改数组元素位置。我从来没有这样做过，所以不知道怎么用数组做这个。我在这里发布我的数组结果。

第一个（主要）数组：

Array
(
    [0] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1201
        )

    [1] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1200
        )

    [2] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1196
        )

    [3] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1193
        )

    [4] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1191
        )

    [5] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1145
        )

    [6] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1144
        )

    [7] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1139
        )

    [8] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1135
        )

    [9] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1053
        )
)

第二阵列：

Array
(
    [0] => stdClass Object
        (
            [bounced_id] => 2
            [user_id] => 156
            [property_id] => 1193
        )

    [1] => stdClass Object
        (
            [bounced_id] => 1
            [user_id] => 156
            [property_id] => 1191
        )

    [2] => stdClass Object
        (
            [bounced_id] => 26
            [user_id] => 156
            [property_id] => 1200
        )
)

我想要这个数组结果：

Array
(
    [0] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1193
        )

    [1] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1191
        )

    [2] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1200
        )


    [3] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1201
        )

    [4] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1196
        )

    [5] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1145
        )

    [6] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1144
        )

    [7] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1139
        )

    [8] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1135
        )

    [9] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1053
        )
)

Answer 1

一种方法是循环数组和容器。在循环下，如果您的特定键匹配，将项目放在第一个匹配的项目（过滤类别），然后在完成后，合并其余项目。

$result = array(); // container
foreach($array2 as $k2 => $val2) {
    foreach($array1 as $k1 => $val1) {
        if($val2->property_id == $val1->property_id) { // if it matches
            $result[] = $val1; // put it inside
            unset($array2[$k2], $array1[$k1]); // remove to continue next set
            break;
        }
    }
}
$result = array_merge($result, $array1); // merge the rest

Sample Output

Answer 2

如果我理解正确 - 您需要找到第一个和第二个之间的差异，然后将该元素附加到第二个数组

$array_diff = array_diff($first,$second);
$array_result = array_merge($second, $array_diff);

如何在php中基于第二个数组更改数组位置
