I need help with time(), timestamp..

Hello,

If its been over 1 hour since the time stamp was created I want to echo 'Error'
but if its under 1 hour since the time stamp was created I want it to echo 'Okay'

the only bit of code I have is

$now = time();
$timestamp = $row['timestamp'];

PHP:

Thanks.

 

I image your idea is when user login, system recorded time stamp is T1 and if user online over 1 hour will get message "Time out". It's right?
Where and how did you store time stamp? I try:

$past = time();
// Record it to Database or use cookie/session

Make a js script (setTimeout() function) to check active $now = time() for each 10s (maybe more if you like)

if ($now - $past < 3600) {
     echo "Okay";
} else {
     echo "Error";
}

Code (markup):

 

Thanks, it seam's to work.
