Bağımsız Değişkenler

specification

A subset of the » ISO 8601 repeating interval specification.

An example of an accepted ISO 8601 interval specifications is R5/2008-03-01T13:00:00Z/P1Y2M10DT2H30M, which specifies:

  • 5 iterations (R5/)
  • Starting at 2008-03-01T13:00:00Z.
  • Each iteration is an 1 year, 2 months, 10 days, 2 hours, and 30 minute interval (/P1Y2M10DT2H30M).

Examples of some ISO 8601 interval specification features that PHP does not support are:

  1. zero occurrences (R0/)
  2. time offsets other than UTC (Z), such as +02:00.
options

A bit field which can be used to control certain behaviour with start- and end- dates.

With DatePeriod::EXCLUDE_START_DATE you exclude the start date from the set of recurring dates within the period.

With DatePeriod::INCLUDE_END_DATE you include the end date in the set of recurring dates within the period.
