示例 #1 datefmt_set_pattern() example
<?php
$fmt = datefmt_create(
'en_US',
IntlDateFormatter::FULL,IntlDateFormatter::FULL,
'America/Los_Angeles',
IntlDateFormatter::GREGORIAN,
'MM/dd/yyyy'
);
echo 'Pattern of the formatter is : ', datefmt_get_pattern($fmt), PHP_EOL;
echo 'First Formatted output with pattern is ', datefmt_format($fmt, 0), PHP_EOL;
datefmt_set_pattern($fmt, 'yyyyMMdd hh:mm:ss z');
echo 'Now pattern of the formatter is : ', datefmt_get_pattern($fmt), PHP_EOL;
echo 'Second Formatted output with pattern is ', datefmt_format($fmt, 0), PHP_EOL;
?>
示例 #2 OO example
<?php
$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;
?>
以上示例会输出:
Pattern of the formatter is : MM/dd/yyyy First Formatted output is 12/31/1969 Now pattern of the formatter is : yyyyMMdd hh:mm:ss z Second Formatted output is 19691231 04:00:00 PST
