Here is a simple example: https://www.w3schools.com/PHP/php_file_create.asp

Error handling not the perfect one, but you will be able to improve.

To read the data in the file to a string you can use file_get_contents,
see http://www.php.net/manual/en/function.file-get-contents.php

And then convert it to an integer, use intval, see
http://php.net/manual/en/function.intval.php
