推荐答案

您可以尝试一下.

首先，解码您的JSON:

Firstly, decode your JSON:

$json_object = file_get_contents('some_file_name.json');
$data = json_decode($json_object, true);

然后编辑所需内容，例如:

Then edit what you want such as:

$data['some_key'] = "some_value";

最后将其重新写到文件(或更新的文件)上:

Finally rewrite it back on the file (or a newer one):

$json_object = json_encode($data);
file_put_contents('some_file_name.json', $json_object);

注意:我假设JSON来自文件，但是您可以很好地使用返回JSON对象的任何东西来代替该文件系统功能.

---

Note: I assumed that the JSON comes from a file, but in place of that file system function you can very well use anything that returns a JSON object.
