echo "Default pattern: '" . msgfmt_get_pattern( $fmt ) . "'\n";
echo "Formatting result: " . msgfmt_format( $fmt, array(123, 456) ) . "\n";
msgfmt_set_pattern( $fmt, "{0, number} trees hosting {1, number} monkeys" );
echo "New pattern: '" . msgfmt_get_pattern( $fmt ) . "'\n";
echo "Formatted number: " . msgfmt_format( $fmt, array(123, 456) ) . "\n";
?>`

示例 #2 OO example

`<?php
$fmt = new MessageFormatter( "en_US", "{0, number} monkeys on {1, number} trees" );
echo "Default pattern: '" . $fmt->getPattern() . "'\n";
echo "Formatting result: " . $fmt->format(array(123, 456)) . "\n";
$fmt->setPattern("{0, number} trees hosting {1, number} monkeys" );
echo "New pattern: '" . $fmt->getPattern() . "'\n";
echo "Formatted number: " . $fmt->format(array(123, 456)) . "\n";
?>`

    Default pattern: '{0,number} monkeys on {1,number} trees'
    Formatting result: 123 monkeys on 456 trees
    New pattern: '{0,number} trees hosting {1,number} monkeys'
