The DatePeriod class

(PHP 5 >= 5.3.0, PHP 7, PHP 8)

Introduction

Represents a date period.

A date period allows iteration over a set of dates and times, recurring at regular intervals, over a given period.

class DatePeriod implements IteratorAggregate {

/* Constants */

const int EXCLUDE_START_DATE = 1;

/* Properties */

public int $recurrences;

public bool $include_start_date;

public DateTimeInterface $start;

public DateTimeInterface $current;

public DateTimeInterface $end;

public DateInterval $interval;

/* Methods */

public __construct(
    DateTimeInterface $start,
    DateInterval $interval,
    int $recurrences,
    int $options = 0
)

public __construct(
    DateTimeInterface $start,
    DateInterval $interval,
    DateTimeInterface $end,
    int $options = 0
)

public __construct(string $isostr, int $options = 0)

public getRecurrences(): ?int

}

DatePeriod::EXCLUDE_START_DATE: Exclude start date, used in DatePeriod::__construct().

recurrences: The number of recurrences, if the DatePeriod instance had been created by explicitly passing $recurrences. See also DatePeriod::getRecurrences().
include_start_date: Whether to include the start date in the set of recurring dates or not.
start: The start date of the period.
current: During iteration this will contain the current date within the period.
end: The end date of the period.
interval: An ISO 8601 repeating interval specification.

Version	Description
