我想對(duì) json 數(shù)據(jù)進(jìn)行排序，但排序顯示錯(cuò)誤。這是什么原因？下面是我的數(shù)據(jù)庫(kù)表的名稱，我在下面給出了頁(yè)面列名稱page_content和 json 數(shù)據(jù)。我哪里出錯(cuò)了？我是新來(lái)的。如果您采取相應(yīng)行動(dòng)，請(qǐng)感到高興。數(shù)據(jù)庫(kù)數(shù)據(jù)page_content{    "kind":"video",    "etag":"edtags",    "id":"id",    "statistics":{        "viewCount":"1434348",    }}{    "kind":"video",    "etag":"edtags",    "id":"id",    "statistics":{        "viewCount":"16058462",    }}{    "kind":"video",    "etag":"edtags",    "id":"id",    "statistics":{        "viewCount":"2176846",    }}{    "kind":"video",    "etag":"edtags",    "id":"id",    "statistics":{        "viewCount":"8088410",    }}{    "kind":"video",    "etag":"edtags",    "id":"id",    "statistics":{        "viewCount":"9885758",    }}{    "kind":"video",    "etag":"edtags",    "id":"id",    "statistics":{        "viewCount":"26795682",    }}{    "kind":"video",    "etag":"edtags",    "id":"id",    "statistics":{        "viewCount":"323810",    }}{    "kind":"video",    "etag":"edtags",    "id":"id",    "statistics":{        "viewCount":"529588",    }}{    "kind":"video",    "etag":"edtags",    "id":"id",    "statistics":{        "viewCount":"6416534",    }}索引.php$query = $db->query('SELECT * FROM pages order by JSON_EXTRACT(page_content,"$.statistics.viewCount") ASC');$query->execute();$row = $query->fetchAll(PDO::FETCH_ASSOC);if ($row ) {    foreach ($row as $value) {        $json = json_decode($value['page_content'], true);        $videoView = $json['statistics']['viewCount'];        echo $videoView;    }}打印_r988575880884106416534529588323810267956822176846160584621434348
