使用元素内部的多个键对数组元素进行排序-PHP

我已经将数组转换为JSON，如下所示：

[
    {
        "name": "Sally",
        "nick_name": "sal",
        "availability": "0",
        "is_fav": "0"
    },
    {
        "name": "David",
        "nick_name": "dav07",
        "availability": "0",
        "is_fav": "1"
    },
    {
        "name": "Zen",
        "nick_name": "zen",
        "availability": "1",
        "is_fav": "0"
    },
    {
        "name": "Jackson",
        "nick_name": "jack",
        "availability": "1",
        "is_fav": "1"
    },
    {
        "name": "Rohit",
        "nick_name": "rod",
        "availability": "0",
        "is_fav": "0"
    },

]

我想根据的值按以下顺序整个数组进行排序is_fav，availability以及nick_name：

[ is_fav:1 availability:1 ]
[ is_fav:1 availability:0 ]
[ is_fav:0 availability:1 ]
[ is_fav:0 availability:0 ]

在这些条件中的每一个条件下，元素都按字母顺序使用 nick_name

因此，上面示例中的最终数组看起来像

[
    {
        "name": "Jackson",
        "nick_name": "jack",
        "availability": "1",
        "is_fav": "1"
    },
    {
        "name": "David",
        "nick_name": "dav07",
        "availability": "0",
        "is_fav": "1"
    },
    {
        "name": "Zen",
        "nick_name": "zen",
        "availability": "1",
        "is_fav": "0"
    },
    {
        "name": "Rohit",
        "nick_name": "rod",
        "availability": "0",
        "is_fav": "0"
    },
    {
        "name": "Sally",
        "nick_name": "sal",
        "availability": "0",
        "is_fav": "0"
    },
]

试试这个array_multisort

$arr = json_decode($data, true);
// Obtain a list of columns
foreach ($arr as $key => $row) {
    $isFav[$key] = $row['is_fav'];
    $avail[$key] = $row['availability'];
    $names[$key] = $row['nick_name'];
}

// Sort the data with isFav descending, avail descending
// Add $arr as the last parameter, to sort by the common key
array_multisort($isFav, SORT_DESC, $avail, SORT_DESC, $names, SORT_ASC, $arr);
