IntlCalendar::createInstance — Create a new IntlCalendar

### Description

Object-oriented style

public static IntlCalendar::createInstance(IntlTimeZone|DateTimeZone|string|null `$timezone` = `null`, ?string `$locale` = `null`): ?IntlCalendar

Procedural style

intlcal_create_instance(IntlTimeZone|DateTimeZone|string|null `$timezone` = `null`, ?string `$locale` = `null`): ?IntlCalendar

Given a timezone and locale, this method creates an IntlCalendar object. This factory method may return a subclass of IntlCalendar.

The calendar created will represent the time instance at which it was created, based on the system time. The fields can all be cleared by calling IntCalendar::clear() with no arguments. See also IntlGregorianCalendar::__construct().

### Parameters

`timezone`

  The timezone to use.

  - `null`, in which case the default timezone will be used, as specified in the ini setting date.timezone or through the function date_default_timezone_set() and as returned by date_default_timezone_get().

  - An IntlTimeZone, which will be used directly.

  - A DateTimeZone. Its identifier will be extracted and an ICU timezone object will be created; the timezone will be backed by ICUʼs database, not PHPʼs.

  - A string, which should be a valid ICU timezone identifier. See IntlTimeZone::createTimeZoneIDEnumeration(). Raw offsets such as `"GMT+08:30"` are also accepted.

`locale`

  A locale to use or `null` to use the default locale.

### Return Values

The created IntlCalendar instance or `null` on failure.

### Examples

Example #1 IntlCalendar::createInstance()

`<?php
ini_set('intl.default_locale', 'es_ES');
ini_set('date.timezone', 'Europe/Madrid');
$cal = IntlCalendar::createInstance();
echo "No arguments\n";
var_dump(get_class($cal),
IntlDateFormatter::formatObject($cal, IntlDateFormatter::FULL));
echo "\n";
echo "Explicit timezone\n";
$cal = IntlCalendar::createInstance(IntlTimeZone::getGMT());
var_dump(get_class($cal),
IntlDateFormatter::formatObject($cal, IntlDateFormatter::FULL));
echo "\n";
echo "Explicit locale (with calendar)\n";
$cal = IntlCalendar::createInstance(NULL, 'es_ES@calendar=persian');
var_dump(get_class($cal),
IntlDateFormatter::formatObject($cal, IntlDateFormatter::FULL));`

The above example will output:

    No arguments
    string(21) "IntlGregorianCalendar"
    string(68) "martes 18 de junio de 2013 14:11:02 Hora de verano de Europa Central"

    Explicit timezone
    string(21) "IntlGregorianCalendar"
    string(45) "martes 18 de junio de 2013 12:11:02 GMT+00:00"

    Explicit locale (with calendar)
    string(12) "IntlCalendar"
    string(70) "martes 28 de Khordad de 1392 14:11:02 Hora de verano de Europa Central"
