How to export variable data to a JSON file on the server using JavaScript/PHP?

So let's say I have a HTML page and an input box on it. The user will type something in it, then I'll store it as a variable in JS, and then, can I somehow write the data of that variable to an already existing JSON file on the server?

How can I achieve this using JavaScript and/or PHP?

EDIT: I actually want to know how to write the data of a PHP variable to a JSON file that is in the same directory as the PHP file.

file_put_contents("json_file.json",json_encode($array));
Result:
{"key":"value","anotherkey":"anothervalue"}

Note: file_put_contents function will overwrite your file!

Edit: appendable: 
$array = json_decode(file_get_contents("json_file.json"),true);
$array['your_new_key'] = "your_new_value";
file_put_contents("json_file.json",json_encode($array));
