使用PHP的Json格式

我想像这样输出JSON：

[{"item":{"id":"id1","label":"Lorem ipsum dolor 1","checked":false},"children":[{"item":{"id":"id11","label":"Lorem ipsum dolor 11","checked":false}},{"item":{"id":"id12","label":"Lorem ipsum dolor 12","checked":false}},{"item":{"id":"id13","label":"Lorem ipsum dolor 13","checked":false}}]}]

我有以下PHP代码：

您可以这样做

json_encode($json_variable);

试试这个：

首先，使用PHP可以创建具有此结构的数组，然后使用json_encode函数：

$array = array(
array(
    "item" => 
        array("id" => "id1", "label" => "Lorem ipsum dolor 1", "checked" => false),
        "children" => 
        array(
            array("item"=>array("id" => "id11", "label" => "Lorem ipsum dolor 11", "checked" => false)),
            array("item"=>array("id" => "id12", "label" => "Lorem ipsum dolor 12", "checked" => false)),
            array("item"=>array("id" => "id13", "label" => "Lorem ipsum dolor 13", "checked" => false)),
     )
  )
);

$json_data = json_encode($array);
echo $json_data;

输出：

[{"item":{"id":"id1","label":"Lorem ipsum dolor 1","checked":false},"children":[{"item":{"id":"id11","label":"Lorem ipsum dolor 11","checked":false}},{"item":{"id":"id12","label":"Lorem ipsum dolor 12","checked":false}},{"item":{"id":"id13","label":"Lorem ipsum dolor 13","checked":false}}]}]

显示您尝试过的代码如何显示代码，我认为您可能会从DB获得assoc或API结果，然后尝试将其转换为JSON。对吗？更新我的密码plz检查
