- Object Oriented Style:
DateTime DateTime::add (DateInterval $interval)
- Procedural style:
DateTime date_add (DateTime $object, DateInterval $interval)
- $object:specifies the DateTime object returned by the date_create() function. This function returns a new DateTime object.
- $interval:this parameter contains a DateInterval object.
// Initializing DateTime $datetime = new DateTime ( ’2019-09-30’ );
// DateInterval object is taken as
// add() function parameter
// 1 day has been added here $datetime -> add ( new DateInterval ( ’P1D’ ));
// Get a new date after adding echo $datetime -> format ( ’Ymd’ ). "" ; ?> Exit:2019-10 -01
Program 2:
// Initialize DateTime $datetime = new DateTime ( ’2019-09-30’ );
// DateInterval object is taken as
// add() function parameter
// Added 5 hours, 3 minutes and 10 seconds here $datetime -> add ( new DateInterval ( ’PT5H3M10S’ ));
// Get a new date after adding echo $datetime -> format ( ’Ymd H: i: s’ ). "" ; ?> Exit:2019-09 -30 05:03:10
