IntlCalendar::toDateTime — Convert an IntlCalendar into a DateTime object

说明

面向对象风格

public IntlCalendar::toDateTime(): DateTime|false

过程化风格

intlcal_to_date_time(IntlCalendar $calendar): DateTime|false

Create a DateTime object that represents the same instant (up to second precision, with a rounding error of less than 1 second) and has an analog timezone to this object (the difference being DateTimeʼs timezone will be backed by PHPʼs timezone while IntlCalendarʼs timezone is backed by ICUʼs).

参数

calendar: IntlCalendar 实例。

返回值

A DateTime object with the same timezone as this object (though using PHPʼs database instead of ICUʼs) and the same time, except for the smaller precision (second precision instead of millisecond). Returns false on failure.

范例

示例 #1 IntlCalendar::toDateTime()


<?php
ini_set('date.timezone', 'UTC');
ini_set('intl.default_locale', 'pt_PT');

$cal = IntlCalendar::createInstance('Europe/Lisbon'); //current time

$dt = $cal->toDateTime();
print_r($dt);

以上例程会输出：

DateTime Object
(
    [date] => 2013-07-02 00:29:13
    [timezone_type] => 3
    [timezone] => Europe/Lisbon
)
