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.
