说明

面向对象风格

public IntlCalendar::isEquivalentTo(IntlCalendar $other): bool

过程化风格

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

Returns whether this and the given object are equivalent for all purposes except as to the time they have set. The locales do not have to match, as long as no change in behavior results from such mismatch. This includes the timezone, whether the lenient mode is set, the repeated and skipped wall time settings, the days of the week when the weekend starts and ceases and the times where such transitions occur. It may also include other calendar specific settings, such as the Gregorian/Julian transition instant.

参数

calendar: IntlCalendar 实例。
other: The other calendar against which the comparison is to be made.

返回值

Assuming there are no argument errors, returns true if the calendars are equivalent except possibly for their set time.

范例

示例 #1 IntlCalendar::isEquivalentTo()


<?php
$cal1 = IntlCalendar::createInstance('Europe/Lisbon', 'pt_PT');
$cal2 = IntlCalendar::createInstance('Europe/Lisbon', 'es_ES');
$cal2->clear();

var_dump($cal1->isEquivalentTo($cal2)); // true

$cal3 = IntlCalendar::createInstance('Europe/Lisbon', 'en_US');
var_dump($cal1->isEquivalentTo($cal3)); // false
var_dump($cal1->getFirstDayOfWeek(),    // 2 (Monday)
$cal3->getFirstDayOfWeek());            // 1 (Sunday)

以上例程会输出：

bool(true)
bool(false)
int(2)
int(1)
