I have generated ICS file through PHP & JS .

BEGIN:VCALENDAR

LOCATION:6760 Painter Ave, Whittier, CA 90601
END:VEVENT
END:VCALENDAR

When I import this file in outlook, end date is shown as 11th March though it is 12th March. How can I fix this?

According to the spec, the end of an allday event is the beginning of the next day. So a 1 day event in the ics file will have 2 dates - the DTEND will be the day after the DTSTART. So in our case, to make it look like it ends on the 12th in applications, the .ics file must say 13th. See also Exclusive/Inclusive DTEND according to RFC5545 and Fullcalendar in event with time part, how to do it right?
