Returns the formatted interval. NOTES
Note The DateInterval::format method does not recalculate carry over points in time strings nor in date segments. This is expected because it is not possible to overflow values like "32 days" which could be interpreted as anything from "1 month and 4 days" to "1 month and 1 day". EXAMPLES
Example #1 DateInterval example <?php $interval = new DateInterval('P2Y4DT6H8M'); echo $interval->format('%d days'); ?> The above example will output: 4 days Example #2 DateInterval and carry over points <?php $interval = new DateInterval('P32D'); echo $interval->format('%d days'); ?> The above example will output: 32 days Example #3 DateInterval and DateTime::diff with the %a and %d modifiers <?php $january = new DateTime('2010-01-01'); $february = new DateTime('2010-02-01'); $interval = $february->diff($january); // %a will output the total number of days. echo $interval->format('%a total days')." "; // While %d will only output the number of days not already covered by the // month. echo $interval->format('%m month, %d days'); ?> The above example will output: 31 total days 1 month, 0 days SEE ALSO
