Hi, I 'm in need of help, I need to code a timer for a turn based txt based rpg game using SQL and PHP, I have a small idea of how this'd work but not sure I was thinking of using:

/* $time = (time()  - time()+ 60); unix time blah blah + 60 seconds which is inserted into the table (the array is $userrow[];) */
$usertime = $userrow['turn']; //Timestamp with the time above

And I need it to count down from 60 seconds(And I can do the rest)
Thanks to those that are willing to help!
