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 ".datefmt_format( $fmt , 0);
$fmt->setPattern('yyyymmdd hh:mm:ss z');
echo "Now pattern of the formatter is : ".$fmt->getPattern();
echo "Second Formatted output is ".datefmt_format( $fmt , 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
