The DateTimeImmutable class

(PHP 5 >= 5.5.0, PHP 7)

简介

This class behaves the same as DateTime except it never modifies itself but returns a new object instead.

DateTimeImmutable implements DateTimeInterface {

/* 方法 */

public __construct ([ string $time = "now" [, DateTimeZone $timezone = NULL ]] )

public DateTimeImmutable add ( DateInterval $interval )

public static DateTimeImmutable createFromFormat ( string $format , string $time [, DateTimeZone $timezone ] )

public static DateTimeImmutable createFromMutable ( DateTime $datetime )

public static array getLastErrors ( void )

public DateTimeImmutable modify ( string $modify )

public static DateTimeImmutable __set_state ( array $array )

public DateTimeImmutable setDate ( int $year , int $month , int $day )

public DateTimeImmutable setISODate ( int $year , int $week [, int $day = 1 ] )

public DateTimeImmutable setTime ( int $hour , int $minute [, int $second = 0 [, int $microseconds = 0 ]] )

public DateTimeImmutable setTimestamp ( int $unixtimestamp )

public DateTimeImmutable setTimezone ( DateTimeZone $timezone )

public DateTimeImmutable sub ( DateInterval $interval )

public DateInterval diff ( DateTimeInterface $datetime2 [, bool $absolute = false ] )

public string format ( string $format )

public int getOffset ( void )

public int getTimestamp ( void )

public DateTimeZone getTimezone ( void )

public __wakeup ( void )

}
