The DateTimeInterface interface

(PHP 5 >= 5.5.0, PHP 7)

Introducere

DateTimeInterface is meant so that both DateTime and DateTimeImmutable can be type hinted for. It is not possible to implement this interface with userland classes.

Sinopsisul clasei

DateTimeInterface {
/* Constante */
const string ATOM = "Y-m-d\TH:i:sP" ;
const string COOKIE = "l, d-M-Y H:i:s T" ;
const string ISO8601 = "Y-m-d\TH:i:sO" ;
const string RFC822 = "D, d M y H:i:s O" ;
const string RFC850 = "l, d-M-y H:i:s T" ;
const string RFC1036 = "D, d M y H:i:s O" ;
const string RFC1123 = "D, d M Y H:i:s O" ;
const string RFC2822 = "D, d M Y H:i:s O" ;
const string RFC3339 = "Y-m-d\TH:i:sP" ;
const string RFC3339_EXTENDED = "Y-m-d\TH:i:s.vP" ;
const string RSS = "D, d M Y H:i:s O" ;

Constante predefinite

DateTimeInterface::ATOM
DATE_ATOM
Atom (example: 2005-08-15T15:52:01+00:00)
DateTimeInterface::COOKIE
DATE_COOKIE
HTTP Cookies (example: Monday, 15-Aug-2005 15:52:01 UTC)
DateTimeInterface::ISO8601
DATE_ISO8601
ISO-8601 (example: 2005-08-15T15:52:01+0000)

Notă: This format is not compatible with ISO-8601, but is left this way for backward compatibility reasons. Use DateTime::ATOM or DATE_ATOM for compatibility with ISO-8601 instead.

DateTimeInterface::RFC822
DATE_RFC822
RFC 822 (example: Mon, 15 Aug 05 15:52:01 +0000)
DateTimeInterface::RFC850
DATE_RFC850
RFC 850 (example: Monday, 15-Aug-05 15:52:01 UTC)
DateTimeInterface::RFC1036
DATE_RFC1036
RFC 1036 (example: Mon, 15 Aug 05 15:52:01 +0000)

RFC 2822 (example: Mon, 15 Aug 2005 15:52:01 +0000)
DateTimeInterface::RFC3339

Same as DATE_ATOM (since PHP 5.1.3)
DateTimeInterface::RFC3339_EXTENDED
DATE_RFC3339_EXTENDED
RFC 3339 EXTENDED format (since PHP 7.0.0) (example: 2005-08-15T15:52:01.000+00:00)
DateTimeInterface::RSS
DATE_RSS
RSS (example: Mon, 15 Aug 2005 15:52:01 +0000)

Istoricul schimbărilor

Versiune Descriere
7.2.0 The class constants of DateTime are now defined on DateTimeInterface.
5.5.8 Trying to implement DateTimeInterface raises a fatal error now. Formerly implementing the interface didn't raise an error, but the behavior was erroneous.
