Question

I have some functionality that depends on whether something has already happened in time.
Currently, I do something like this:

$hike_time = strtotime($month.'/'.$day.'/'.$year.' '.$start_time);
if($hike_time < mktime())
{
  // Do stuff :)
}

But I need to wait a day or twelve hours (not sure yet) until I change the functionality.
How can I make the mktime() be +1 day or +12 hours?

In terms of UX, how are such event-based UX quirks typically handled?

Answer 1

You can use strtotime().

$tomorrow = strtotime('+1 day');

var_dump(
   date(DATE_RFC850, time()), // string(30) "Monday, 28-Mar-11 05:48:47 UTC"
   date(DATE_RFC850, $tomorrow) // string(31) "Tuesday, 29-Mar-11 05:48:47 UTC"
);
