如何从客户端修改存储在服务器上的 a.JSON 文件？

Question

I'm working on a webapp that is currently running on a server, where there are also some.JSON files, which I would like the user to be able to type some information and press enter where it will be stored to the.JSON file.

The webapp is written in HTML, CSS, and vanilla Javascript, there aren't any external libraries being used.

I am already pulling information from the.JSON files to be used in the app using the GET function, and I know I can't directly modify server side files with javascript unless I'm running a Node.js server (which isn't currently an option).

So I believe my only option is to use a server side language such as PHP (which I nothing about), to modify the file. My question is, how can I do this relatively simply? Possibly when a JS function is run to push the change to the file.

Can anyone give me a sliver of example code, or point me in the direction of some simple documentation or tutorial on how to do this, I'm not very adept at server side programming at all, and as this is a simple project just for me, I don't want to dive deep into PHP at the moment.

Thank you in advanced!

Since you already know JavaScript, I'd revisit why you feel you can't use Node.js server-side. In any case, if you're going ahead with PHP...

To write files, file_put_contents() .

To encode JSON, json_encode() .

Note that there are other servers out there. You don't have to write your own stuff in PHP. If you don't need any checking on what's being sent, you can probably even modify your web server's config to accept a PUT .
