time out in a web page

[streetfi8er]

i am creating an online exam form through php .. so what should i do if i wan the page to expire after a examinee has spent 3 hours on the page?

you could use sessions.

 

$_SESSION['startime'] = microtime(TRUE);

 

then when the user goes to submit the test, just do a check like this:

 

$maxTime = 10800; // 3 hours (time in seconds)
if((microtime(TRUE) - $_SESSION['startime']) > $maxTime){
   echo 'You took too long';
}else{
   echo 'Thank You! You are done!';
}

save a time stamp in the database, use ajax to keep refreshing the page,

 

if the time == 3hrs then submit current information and send them to a warning page,

but let them see there  current results.

 

could be also doNE in php where they can not enter no more information in the database when the time has reached 3 hours.
