The IntlDateFormatter class

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL intl >= 1.0.0)

简介

Date Formatter is a concrete class that enables locale-dependent formatting/parsing of dates using pattern strings and/or canned patterns.

This class represents the ICU date formatting functionality. It allows users to display dates in a localized format or to parse strings into PHP date values using pattern strings and/or canned patterns.

预定义常量

These constants are used to specify different formats in the constructor for DateType and TimeType.

IntlDateFormatter::NONE
Do not include this element
IntlDateFormatter::FULL
