在多维数组Array_slice？但不同的输出

Question

我有这样的PHP数组：

     $multid_array = array(
        "url" => "www.checkmyhouse.cpm",
        "date" => "2019/12/12",
        "minor" => 1,
        "sittingroom" => 1,
        "dinningroom" => 2,
        "toilet" => 2,
        "parking" => 1,
        "bedroom" => 2,
        "garage" => 2,
        "rooms" => 4,
        "garden" => 1,

        "url_1" => "-sameurl-",
        "date_1" => "2019/12/3",
        "minor_1" => 3,
        "sittingroom_1" => 2,
        "dinningroom_1" => 2,
        "toilet_1" => 3,
        "parking_1" => 1,
        "bedroom_1" => 2,
        "garage_1" => 6,
        "rooms_1" => 6,
        "garden_1" => 1,

        "url_2" => "-sameurl-",
        "date_2" => "2019/12/5",
        "minor_2" => 3,
        "sittingroom_2" => 2,
        "dinningroom_2" => 2,
        "toilet_2" => 3,
        "parking_2" => 1,
        "bedroom_2" => 5,
        "garage_2" => 6,
        "rooms_2" => 9,
        "garden_2" => 1,
    );

我已经四处搜寻，发现了这个链接。但没能弄明白。保持亲近。 array_slice in multidimensional array?

这是我想的输出：

$array =
    [ 
       "levels" => array(
            "0" => array(
                "url" => "www.checkmyhouse.cpm",
                "date" => "2019/12/1",
                "minor" => 1,
                "sittingroom" => 1,
                "dinningroom" => 2,
                "toilet" => 2,
                "parking" => 1,
                "bedroom" => 2,
                "garage" => 2,
                "rooms" => 5,
                "garden" => 1,
            ),
            "1" => array(
                "url" => "-sameurl-",
                "date" => "2019/12/3",
                "minor" => 3,
                "sittingroom" => 2,
                "dinningroom" => 2,
                "toilet" => 3,
                "parking" => 1,
                "bedroom" => 2,
                "garage" => 6,
                "rooms" => 6,
                "garden" => 1,
            ),
            "2" => array(
                "url" => "-sameurl-",
                "date" => "2019/12/5",
                "minor" => 3,
                "sittingroom" => 2,
                "dinningroom" => 2,
                "toilet" => 3,
                "parking" => 1,
                "bedroom" => 5,
                "garage" => 6,
                "rooms" => 9,
                "garden" => 1,
            )
        )
    ];

只是想重新安排它。但我已经使用array_slice，只能获得第9种元素的输出。

array_splice($multid_array,9);

但我想自动运行，这样的情况下，更多的信息被添加到阵列中，然后将仍然有效

为什么不使用简单的for循环：（在这种情况下，你可以在每个阵列中的各个号码字段的，他们并不需要被固定为在使用时array_chunk）

$multid_array = array("url" => "www.checkmyhouse.cpm","date" => "2019/12/12","url_1" => "-sameurl-","date_1" => "2019/12/3","url_2" => "-sameurl-","date_2" => "2019/12/5",);

$ans = [];
foreach($multid_array as $k => $v) {
    $parts = explode("_", $k); 
    $pk = 0; //default as 0 as when no prefix set to key "0"
    if (count($parts) > 1) { // check if has suffix
        $pk = $parts[1];
        $k = $parts[0];
    }
    if (!isset($ans[$pk]))
        $ans[$pk] = []; // init array if first time
    $ans[$pk][$k] = $v;
}

现在$ans将包含您的数据 - 如果你愿意，你可以添加“水平”的关键。

这，如果你有“_”将只能保存标记内索引和他们没有实际使用的密钥
