DateTimeImmutable 类

(PHP 5 >= 5.5.0, PHP 7, PHP 8)

简介

日期和时间的表示。

此类与DateTime 的行为相同,只是当调用DateTime::modify() 等修改方法时,会返回新的对象。

类概要

class DateTimeImmutable implements DateTimeInterface {
/* 继承的常量 */
public const string DateTimeInterface::ATOM = "Y-m-d\\TH:i:sP";
public const string DateTimeInterface::COOKIE = "l, d-M-Y H:i:s T";
public const string DateTimeInterface::ISO8601 = "Y-m-d\\TH:i:sO";
public const string DateTimeInterface::ISO8601_EXPANDED = "X-m-d\\TH:i:sP";
public const string DateTimeInterface::RFC822 = "D, d M y H:i:s O";
public const string DateTimeInterface::RFC850 = "l, d-M-y H:i:s T";
public const string DateTimeInterface::RFC1036 = "D, d M y H:i:s O";
public const string DateTimeInterface::RFC1123 = "D, d M Y H:i:s O";
public const string DateTimeInterface::RFC7231 = "D, d M Y H:i:s \\G\\M\\T";
public const string DateTimeInterface::RFC2822 = "D, d M Y H:i:s O";
public const string DateTimeInterface::RFC3339 = "Y-m-d\\TH:i:sP";
public const string DateTimeInterface::RFC3339_EXTENDED = "Y-m-d\\TH:i:s.vP";
public const string DateTimeInterface::RSS = "D, d M Y H:i:s O";
public const string DateTimeInterface::W3C = "Y-m-d\\TH:i:sP";
/* 方法 */
public __construct(string $datetime = "now", ?DateTimeZone $timezone = null)
public static createFromFormat(string $format, string $datetime, ?DateTimeZone $timezone = null): DateTimeImmutable|false
public static createFromMutable(DateTime $object): static
public static getLastErrors(): array|false
public modify(string $modifier): DateTimeImmutable
public static __set_state(array $array): DateTimeImmutable
public setDate(int $year, int $month, int $day): DateTimeImmutable
public setISODate(int $year, int $week, int $dayOfWeek = 1): DateTimeImmutable
public setTime(


    int $hour,
    int $minute,
    int $second = 0,
    int $microsecond = 0
): DateTimeImmutable

public setTimestamp(int $timestamp): DateTimeImmutable
public diff(DateTimeInterface $targetObject, bool $absolute = false): DateInterval
public format(string $format): string
public getOffset(): int
public getTimestamp(): int
public __wakeup(): void
}

变更日志

版本 描述
8.4.0 类常量现在已添加类型声明。
7.1.0 DateTimeImmutable 构造函数现在包含构造值中的当前微秒数。在此之前,它总是将微秒初始化为 0
