Procedural style

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.
Parameters
cal
The IntlCalendar resource.
other
The other calendar against which the comparison is to be made.
Return Values
Assuming there are no argument errors, returns TRUE iif the calendars are equivalent except possibly for their set time.
Examples
Example #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)
The above example will output:
bool(true)
bool(false)
int(2)
int(1)
