<?php
$fmt 
datefmt_create(
    
'en_US',
    
IntlDateFormatter::FULL,IntlDateFormatter::FULL,
    
'America/Los_Angeles',

echo 
'First Formatted output with pattern is 'datefmt_format($fmt0), PHP_EOL;
datefmt_set_pattern($fmt'yyyyMMdd hh:mm:ss z');
echo 
'Now pattern of the formatter is : 'datefmt_get_pattern($fmt), PHP_EOL;
echo 
'Second Formatted output with pattern is 'datefmt_format($fmt0), PHP_EOL;
?>

示例 #2 OO example

$fmt 
= new IntlDateFormatter(
    
'en_US',
    
IntlDateFormatter::FULL,IntlDateFormatter::FULL,
    
'America/Los_Angeles',
    
IntlDateFormatter::GREGORIAN,
    
'MM/dd/yyyy'
);
echo 
'Pattern of the formatter is : '$fmt->getPattern(), PHP_EOL;
echo 
'First Formatted output is '$fmt->format(0), PHP_EOL;
$fmt->setPattern('yyyyMMdd hh:mm:ss z');
echo 
'Now pattern of the formatter is : '$fmt->getPattern(), PHP_EOL;
echo 
'Second Formatted output is '$fmt->format(0), PHP_EOL;
?>

以上例程会输出:
