I found myself working on a similar problem - which is how I got to this question in the first place - but just needed a difference in hours. I voted for jurka's answer as that's my favorite, but I have a pre-php.5.3 version. $difference = $first_date->diff($second_date) * If the interval doesn't have a time component (years, months, etc)įunction format_interval(DateInterval $interval) ![]() * Format an interval to show all existing components. To format the DateInterval object, we'll need check each value and exclude it if it's 0: /** A var_dump() looks like this: object(DateInterval) $difference now holds a DateInterval object with the difference information. ![]() If an even more specific date format is needed, DateTime::createFromFormat() can be used to create the DateTime object.Īfter both objects were instantiated, you substract one from the other with DateTime::diff(). The DateTime object will accept any format strtotime() would. Each date is encapsulated in a DateTime object, and then a difference between the two can be made: $first_date = new DateTime(" 17:03:30") The best course of action is using PHP's DateTime (and DateInterval) objects. Print_r(_date_diff(time(), strtotime($date))) Print_r(_date_diff(strtotime($date), time())) $b = array_combine($key, array_map("intval", explode(" ", date("Y m d H i s", $two)))) $a = array_combine($key, array_map("intval", explode(" ", date("Y m d H i s", $one)))) $result = _date_range_limit_days(&$base, &$result) $result -= $adj * intval($result / $adj) įunction _date_range_limit_days($base, $result)
