detecting REFRESH through PHP

[RootShell]

Hello

I need to have a way to check if the user as refreshed the current page.

Is there any way in PHP to do this?

Here's the full facts,

I have a JavaScript running that is merely a 30 seconds countdown, so that
the user has only 30 seconds to answer a question.

The problem is that *IF* he refreshs the page the counter goes up again to
30, and that's is not good ;)

i can do whatever i want when the timer reaches 0.

But i was looking for some sort of control to check if the page was loaded
normally, or refreshed.

(i also thought of a MySQL flag, that would be 0 when page is loaded, and
then when reloaded it would check to see if the flag is 0 or 1, and act
accordingly, but somehow i think that there might be a simplier way).

PS: I *dont* want to prevent the refresh I just want to know when/if it
happened.

Please help,

Thanks

Here's the full facts,

<snip>

a) Set question; record time page was sent, plus IP address, etc.
b) Receive response (or not, in which case, quit).
c) Check receipt time against set time. If >30 seconds, user loses. If page
re-requested to same IP, user loses. It's your rules, after all.

You can't force this sort of thing client side, you need client-side
processing to do that. Consider Flash or something for the client, and keep
PHP the provision of the data.

Start a session for each user.
Add every requested page to a stack in that $_SESSION.

You can set a cookie, and increment it every time the user refreshes a
page. This works for people who have cookie enabled (90%+), but might
be good enough for your app.

PHP tip from a fortune cookie: Don't try to solve a client-side problem on
the server side.

The solution is quite simple: Use Javascript to keep a counter in a cookie.
When the page loads initially, the script will notice that the cookie
variable isn't set and will set it to 30. A timer function attached using
setInterval() will decrement the counter by one every second. Now if the
user refreshes the page, the counter won't get reset since cookies are
persistent.

issue a "one time ticket" for the page, i.e. call it with
kviz.php?oneTit meTicket=122177 d4880ad8e6b9d0c ae5728fd5bf

the first time page gets loaded, in the db mark the ticket as used (or
remove it from your list of valid tickets, depending on your approach).
