IntlCalendar::equals
(PHP 5.5.0, PHP 7, PECL >= 3.0.0a1)
IntlCalendar::equals — Compare time of two IntlCalendar objects for equality
Description
Object oriented style
public bool IntlCalendar::equals ( IntlCalendar $other )
Procedural style
bool intlcal_equals ( IntlCalendar $cal , IntlCalendar $other )
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.
Parameters
-
cal -
The IntlCalendar resource.
-
other -
The calendar to compare with the primary object.
Return Values
Returns TRUE if the current time of both this and the passed in IntlCalendar object are the same, or FALSE otherwise. The value FALSE can also be returned on failure. This can only happen if bad arguments are passed in. In any case, the two cases can be distinguished by calling intl_get_error_code().
Examples
Example #1 IntlCalendar::equals()
<?php
ini_set('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');
$cal2->setTime($cal1->getTime());
var_dump($cal1->equals($cal2)); //TRUE
//And set fields state is not included as well
$cal2->clear(IntlCalendar::FIELD_YEAR);
var_dump($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');
$cal2->setTime($cal1->getTime());
var_dump($cal1->equals($cal2)); //TRUE
//Only the time is
$cal2 = clone $cal1;
$cal2->setTime($cal1->getTime() + 1.);
var_dump($cal1->equals($cal2)); //FALSE
