Php 从一个关联数组弹出并推送到另一个数组

我想从array2跳出来，然后推进array1。 但是根据一些定制要求

现在在数组1中，第一个键的读取顺序是1，第二个键的读取顺序是4

所以我想从array2的前两个键开始，在这两个键之间进行推压。其他所有键的过程都是一样的

我的最终数组必须像array3

例如，在数组1中，键[0]的读取顺序为1，键[1]的读取顺序为4。现在我想按array2的另一个2键。 对于阵列1键[2]，读取顺序为6。因此，在使用此键之前，我想从array2中再按一个键，并继续使用相同的键…

阵列1如下所示

Array
(
    [0] => Array
        (
            [readingOrder] => 1
            [id] => 78
        )

    [1] => Array
        (
            [readingOrder] => 4
            [id] => 76
        )

    [2] => Array
        (
            [readingOrder] => 6
            [id] => 80
        )

)

Array
(
    [0] => Array
        (
            [id] => 81
            [readingOrder] => 2
        )

    [1] => Array
        (
            [id] => 82
            [readingOrder] => 5
        )

    [2] => Array
        (
            [id] => 84
            [readingOrder] => 7
        )

    [3] => Array
        (
            [id] => 85
            [readingOrder] => 8
        )

    [4] => Array
        (
            [id] => 86
            [readingOrder] => 9
        )

    [5] => Array
        (
            [id] => 87
            [readingOrder] => 10
        )

    [6] => Array
        (
            [id] => 88
            [readingOrder] => 11
        )

)

阵列2如下所示

Array
(
    [0] => Array
        (
            [readingOrder] => 1
            [id] => 78
        )

    [1] => Array
        (
            [readingOrder] => 4
            [id] => 76
        )

    [2] => Array
        (
            [readingOrder] => 6
            [id] => 80
        )

)

Array
(
    [0] => Array
        (
            [id] => 81
            [readingOrder] => 2
        )

    [1] => Array
        (
            [id] => 82
            [readingOrder] => 5
        )

    [2] => Array
        (
            [id] => 84
            [readingOrder] => 7
        )

    [3] => Array
        (
            [id] => 85
            [readingOrder] => 8
        )

    [4] => Array
        (
            [id] => 86
            [readingOrder] => 9
        )

    [5] => Array
        (
            [id] => 87
            [readingOrder] => 10
        )

    [6] => Array
        (
            [id] => 88

谢谢。

您可以使用

usort

完成此操作。首先，需要合并阵列：

$a1 = [
    [
        'readingOrder' => 1,
        'id' => 78
    ],
    [
        'readingOrder' => 4,
         'id' => 76
    ],
    [
        'readingOrder' => 6,
        'id' => 80
    ]
];
$a2 = [
    [
        'readingOrder' => 2,
        'id' => 81
    ],
    [
        'readingOrder' => 5,
        'id' => 82
    ],
    [
        'readingOrder' => 7,
        'id' => 84
    ],
    [
        'readingOrder' => 8,
        'id' => 85
    ]
];

$a3 = array_merge($a1, $a2);

然后您需要使用

usort

：

usort($a3, function($a,$b) {
    if ($a['readingOrder'] == $b['readingOrder']) return 0;
    return $a['readingOrder'] < $b['readingOrder'] ? -1 : 1;
});

您可以这样构建阵列：

$current = 1;
$arr3 = [];
while ( $arr1 && $arr2 ) {
    if ( $arr1[0]['readingOrder'] > $current )
        $arr3[] = array_shift($arr2);
    else
        $arr3[] = array_shift($arr1);
    $current++;
}

$arr3 = array_merge($arr3, $arr1, $arr2);

print_r($arr3);

请注意，此代码对

$arr1

和

$arr2

具有破坏性。如果您想保留它们，请先复制它们，然后改用副本。

您以前为获得正确输出所做的尝试是什么样的？更具体地说，你想解决什么问题？@GordonM我编辑了我的问题。现在请阅读。你不明白@GordonM问了什么，问题是：你为什么需要这样做？（你能展示一下你解决问题的努力吗？）这不是他问的问题。@Casimirithippolyte我的错。我必须说，他想要达到的目标也不是很清楚。想要的结果很清楚，但他想这样做的原因是一个很深的谜。@Casimirithippolyte，这让我不清楚哈，事实上我想保持阅读秩序。从array2开始，我想把剩余的位置推给大家。非常感谢。这完全符合我的要求。
