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));
以上例程会输出：
string(20) "01/07/2011, 00:00:00" string(20) "01/07/2012, 00:00:00"
