过程化风格

intlcal_set(IntlCalendar $cal, int $field, int $value): true
intlcal_set(
    IntlCalendar $cal,
    int $year,
    int $month,
    int $dayOfMonth = NULL,
    int $hour = NULL,
    int $minute = NULL,
    int $second = NULL
): bool

Sets either a specific field to the given value, or sets at once several common fields. The range of values that are accepted depend on whether the calendar is using the lenient mode.

For fields that conflict, the fields that are set later have priority.

This method cannot be called with exactly four arguments.

示例

示例 #1 IntlCalendar::set()

<?php
ini_set('date.timezone', 'Europe/Lisbon');
ini_set('intl.default_locale', 'pt_PT');

//Calls made later have priority
$cal = new IntlGregorianCalendar(2013, 6 /* July */, 1);
$cal->set(IntlCalendar::FIELD_YEAR, 2012);
$cal->set(IntlCalendar::FIELD_EXTENDED_YEAR, 2011);
var_dump(IntlDateFormatter::formatObject($cal));


$cal = new IntlGregorianCalendar(2013, 6 /* July */, 1);
$cal->set(IntlCalendar::FIELD_YEAR, 2012);
$cal->set(IntlCalendar::FIELD_EXTENDED_YEAR, 2011);
//the time has not been recalculated yet. If we clear the extended year,
//the year set before will be used
$cal->clear(IntlCalendar::FIELD_EXTENDED_YEAR);
var_dump(IntlDateFormatter::formatObject($cal));

以上示例会输出：

string(20) "01/07/2011, 00:00:00"
string(20) "01/07/2012, 00:00:00"
