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.

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

IntlDateFormatter::NONE: Do not include this element
IntlDateFormatter::FULL: Completely specified style (Tuesday, April 12, 1952 AD or 3:30:42pm PST)
IntlDateFormatter::LONG: Long style (January 12, 1952 or 3:30:32pm)
IntlDateFormatter::MEDIUM: Medium style (Jan 12, 1952)
IntlDateFormatter::SHORT: Most abbreviated style, only essential data (12/13/52 or 3:30pm)
IntlDateFormatter::RELATIVE_FULL: The same as IntlDateFormatter::FULL, but yesterday, today, and tomorrow show as yesterday, today, and tomorrow, respectively. Available as of PHP 8.0.0, for dateType only.
IntlDateFormatter::RELATIVE_LONG: The same as IntlDateFormatter::LONG, but yesterday, today, and tomorrow show as yesterday, today, and tomorrow, respectively. Available as of PHP 8.0.0, for dateType only.
IntlDateFormatter::RELATIVE_MEDIUM: The same as IntlDateFormatter::MEDIUM, but yesterday, today, and tomorrow show as yesterday, today, and tomorrow, respectively. Available as of PHP 8.0.0, for dateType only.
IntlDateFormatter::RELATIVE_SHORT: The same as IntlDateFormatter::SHORT, but yesterday, today, and tomorrow show as yesterday, today, and tomorrow, respectively. Available as of PHP 8.0.0, for dateType only.

The following int constants are used to specify the calendar. These calendars are all based directly on the Gregorian calendar. Non-Gregorian calendars need to be specified in locale. Examples might include locale="hi@calendar=BUDDHIST".

IntlDateFormatter::TRADITIONAL: Non-Gregorian Calendar
IntlDateFormatter::GREGORIAN: Gregorian Calendar
