我想要按频率对元素进行排序（通过“ parrent_club_hash_id”）。
有11-x 7-y和5-z，所以我想要这样的输出：
$result = Array

答案 0 :(得分：0)
首先获取您的值的频率：
$values = array_count_values(array_column($result, 'parrent_club_hash_id'));
然后使用自定义排序按这些频率进行排序：
usort($result, function ($x, $y) use ($values) {
// $y is first because you need descending sort
return $values[$y["parrent_club_hash_id"]] - $values[$x["parrent_club_hash_id"]];
});
