Php 如何将数组中的数组合并到单个数组

我正在尝试将关联数组合并到单个数组，但没有成功

Array
(
    [0] => Array
        (
            [313] => 9513
            [361] => 2280
            [68] => 9513
            [363] => 1591
            [314] => 1610
            [355] => 1908
            [357] => 1445
            [389] => 290

            [362] => 105
            [383] => 28
        )

    [1] => Array
        (
            [385] => 5619
            [4] => 25090
            [45] => 25090
            [321] => 6041

            [318] => 213
            [311] => 138
            [319] => 110
            [382] => 61
        )

    [2] => Array
        (
            [4] => 54098
            [5] => 54098
            [8] => 30669
            [18] => 4880
            [74] => 3457
            [17] => 2702
            [21] => 2217
            [14] => 2216
            [73] => 2109
            [7] => 10085
            [66] => 1969
            [20] => 1481
            [13] => 1234
            [64] => 1180
            [11] => 1097
            [75] => 727
            [15] => 592
            [67] => 767
            [10] => 457
            [391] => 352
            [387] => 356
        )
)

预期产出为：-

如果您不知道元素的数量，最明显的方法是在循环中执行：

$newArray = array();
foreach ($multiarray as $array){
    $newArray = array_merge($newArray,array_values($array));
}

// $newArray contains your flattened array.

但是请注意，不能有多个具有相同键的数组元素-这是不可能的。我已将其设置为丢弃数组键，只保留值-如果您想保留键（但请记住，“较新”的键将覆盖较旧的键，然后删除对数组值的调用（）

@Daan我已经阅读了本教程并尝试了此示例代码，但仍然没有成功。调用用户函数数组（'array\u merge'，$categoryArray）；

array\u merge（$categoryArray[0]、$categoryArray[1]、$categoryArray[2]）

@Daan但是数组维度是动态的，所以我如何实现这一点。@Lim Wiltshire感谢您的回答，我会检查它，并很快让您知道。通过删除array\u值，我仍然不会得到覆盖的键和值对。
