First of all, make sure the status.txt file is in a directory that's
inaccessible from the web (ie. only accessible via your scripts),
preferably one step below the webroot, although not required.
On all my PHP projects, I create a seperate directory called "inc" in
the webroot (or the root directory of my project). If Apache is used, I
place a .htaccess file containing the keyword "deny from all" in it.
Or, if IIS is used (which has happened on a rare occasion), I make sure
all outside access is denied for this directory from the IIS manager.
That way, I protect my code (as well as the base configuration) from
being exposed and/or accessed directly.
Second, make sure your changestatus.php script ONLY reacts to the "on"
or "off" keywords. Or any other keyword you'd like to use instead (such
as "open" or "closed").
Further, to avoid someone outside your organization from setting the
status (such as opening the URL and making it look like you're closed
when you're open for business or vice-versa), you should place this
script under some sort of password protection (either via your CMS or
via a simple basic authentication method).
