The DateTimeInterface interface

(PHP 5 >= 5.5.0, PHP 7)

Вступ

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.

Короткий Огляд Класа

DateTimeInterface {
/* Методи */
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 )
}

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.

if you want to know what all the constants looks like, try

<?php
$constants
= (new ReflectionClass("DateTimeInterface"))->getConstants();
foreach(
$constants as $name => $format){
    echo
"{$name}: " . date($format, 0) . "\n";
}
?>

in php 8.0.3 it prints:
