在第三维对数组进行排序

Question

我尝试按名称对这个数组进行排序，但我编写的函数不起作用

{
"response": {
    "game_count": 175,
    "games": [
        {
            "appid": 4000,
            "name": "Garry's Mod",
            "playtime_forever": 4040,
            "img_icon_url": "4a6f25cfa2426445d0d9d6e233408de4d371ce8b",
            "img_logo_url": "93c9364c3942223ab66195182fe1982af8a16584",
            "has_community_visible_stats": true
        },

按姓名排序，为第三级

我试过了：

function val_sort($array,$key) {

foreach($array as $k=>$v=>$g){
    $b[] = strtolower($v[$key]);
    }
SORT_ASC($b);
foreach($b as $k=>$g=>$v) {
    $c[] = $array[$k];
}

return $c;
}
$sorted = val_sort($array, 'name');

但这对我不起作用。希望你能帮帮我^^

Answer 1

将 foreach 与 usort 结合使用：

foreach ($yourArray["response"] as $key => &$subarray) {
    usort($subarray, function($a, $b) {
    return $a['name'] <= $b['name'];
    });
}
print_r($yourArray); //now it's sorted
