I want to store a number, like "23" inside a file. The number will be the only thing in the file, and it will be incremented whenever I want it to. However - the length of the number can be anything, eg. 429 or 1985409...or whatever - ie. it's *length* can be anything. How do I do this? And of course, how do I read the number inside the file when I want? Thanks.

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. > And of course, how do I read the number inside the file when I want? 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 -- //Aho
