Prozeduraler Stil

intlcal_equals(IntlCalendar $calendar, IntlCalendar $other): bool

Returns true if this calendar and the given calendar have the same time. The settings, calendar types and field states do not have to be the same.



Eine IntlCalendar-Instanz.


The calendar to compare with the primary object.


Returns true if the current time of both this and the passed in IntlCalendar object are the same, or false otherwise.

Bei einem Fehler wird auch false zurückgegeben. Um Fehlerzustände zu erkennen, kann die Funktion intl_get_error_code() verwendet werden oder Intl so konfiguriert werden, dass es Exceptions auslöst.


Beispiel #1 IntlCalendar::equals()

('date.timezone', 'UTC');

$cal1 = IntlCalendar::createInstance(NULL, 'es_ES');
$cal2 = clone $cal1;

var_dump($cal1->equals($cal2)); //TRUE

//The locale is not included in the comparison
$cal2 = IntlCalendar::createInstance(NULL, 'pt_PT');
var_dump($cal1->equals($cal2)); //TRUE

//And set fields state is not included as well
var_dump($cal1->isSet(IntlCalendar::FIELD_YEAR) ==
$cal2->isSet(IntlCalendar::FIELD_YEAR)); //FALSE
var_dump($cal1->equals($cal2)); //TRUE

//Neither is the calendar type
$cal2 = IntlCalendar::createInstance(NULL, 'es_ES@calendar=islamic');
var_dump($cal1->equals($cal2)); //TRUE

//Only the time is
$cal2 = clone $cal1;
$cal2->setTime($cal1->getTime() + 1.);
var_dump($cal1->equals($cal2)); //FALSE
