    Once the book/s is selected from the dropdown listbox the program will automatically set the book’s return date deadline 1 week after the date borrowed. If a book is returned later than that date there will be a penalty of P10 a day.


    Thanks!;)

    Hi zhelpretty02, This is the code that gives you number of days between two dates
    $days = (strtotime(date("Y-m-d"))-strtotime("2009-1-20") ) / (60 * 60 * 24);

    echo $days;

    Now utilize this code according to your program logic.

    If you store a GMT UNIX timestamp keeping track of then the book was checked out.

    if(time() - $checkout_timestamp > 604800)
{
   //book is late
}
    Code (markup):

    Timestamps are in seconds. That's where you gonna start.

    The two codes above should gives you the idea.
