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
