范例
Example #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);echo 'First Formatted output with pattern is ' . datefmt_format($fmt, 0);datefmt_set_pattern($fmt, 'yyyymmdd hh:mm:ss z');echo 'Now pattern of the formatter is : ' . datefmt_get_pattern($fmt);echo 'Second Formatted output with pattern is ' . datefmt_format($fmt, 0);?>
Example #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();echo 'First Formatted output is ' . $fmt->format(0);$fmt->setPattern('yyyymmdd hh:mm:ss z');echo 'Now pattern of the formatter is : ' . $fmt->getPattern();echo 'Second Formatted output is ' . $fmt->format(0);?>
以上例程会输出：
pattern of the formatter is : MM/dd/yyyy First Formatted output with pattern is 12/31/1969 Now pattern of the formatter is : yyyymmdd hh:mm:ss z Second Formatted output with pattern is 19690031 04:00:00 PST
