Question

may I know how do I calculate time left from specific datetime in php?

Example I want user can request a new confirmation code after 30 minute if already requested.

$request_date = '2012-03-24 13:03:17';
$please_wait  = '30 minutes';

How do I calculate the time left?

Answer 1

Time left for new confirmation code:

$request_date = '2012-03-24 13:03:17';
$please_wait  = '30 minutes';
$future_time = strtotime("+" . $please_wait, strtotime($request_date));
$time_left = $future_time - time(); //seconds left
