Timers in php?

[fb]

Hello. I was working on a .php page that asks a user a question, then,
after the submit the answer (multiple choice) it takes data from a
database and makes a new question. Let's say that they have 10
questions to answer. I'd like to give them a time limit to answer these
10 questions. I was wondering if it is possible to make a timer in php,
that counts down and won't reset every time a new question is pulled
from the database (it seems this causes a refresh).

If this is possible, could you please point me towards some code
snippets? Many thanks

While you probably could do it in PHP (i.e. set a cookie with the
current time and check it when they answer), it might be better done
with client-side scripting, i.e. javascript.

The start and finish times need to be set within PHP.
These values must be stored within session variables.
On the web page use AJAX to get the current time every second.
If the user is over the time limit then, on the web page, alert the
user to this fact then, on a click of a button, move to the next
question.

Your ISP might send you a not so nice notice to stop abusing the
system.

Or, if you're going to be using Javascript anyway, no need for the trip
to the server. Just do a client-side timer.

That would allow for the person to change their system clock and
'upset' the timing.

You can make a note of the starting time in PHP to the session, that way
whatever the client do to their clock,
PHP still knows how long it has been.
