在数组中取消设置索引会将其转换为对象

Question

所以我有一个JSON文档，我存储在CouchDB中。这是它的重要部分：

"games": {
   "creator": [
       "cf86d68b24c1bbf22702356572027642",
       "cf86d68b24c1bbf22702356572027dd8",
       "cf86d68b24c1bbf22702356572028b77"
   ],
   "solver": {
   }
}

我正在尝试从数组中删除一个项目，让我们说索引1：

error_log("pre unset: " . json_encode($user->games));
unset($user->games->creator[1]);
error_log("post unset: " . json_encode($user->games));

问题是，它不断将我的数组转换为对象，如下所示：

pre unset: {"creator":["cf86d68b24c1bbf22702356572027642","cf86d68b24c1bbf22702356572027dd8","cf86d68b24c1bbf22702356572028b77"],"solver":{}}
post unset: {"creator":{"0":"cf86d68b24c1bbf22702356572027642","2":"cf86d68b24c1bbf22702356572028b77"},"solver":{}}

发生了什么，我该如何解决？

Answer 1

我这样修好了：

unset($user->games->creator[1]);
$user->games->creator = array_values($user->games->creator);

Answer 2

不使用unset，而是使用array_splice。这将自动调整数组索引：

array_splice($user->games->creator, 1, 1);
