    示例 #1 msgfmt_set_pattern() example

    <?php
    $fmt     = msgfmt_create( "en_US", "{0, number} monkeys on {1, number} trees" );
    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";
    ?>

    以上示例会输出：

    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'
Formatted number: 123 trees hosting 456 monkeys

    A correct example would be to transpose the placeholders in pattern 2.

    This is typical where changing messages from one language to another changes the word order, to result in a sensible translation.

    Let's imagine it's localised as Spanish or Russian instead of English.
    So really you want to have pattern 2 provided by your human translator to read like this :

    New pattern: '{1,number} trees hosting {0,number} monkeys'
    Formatted number: 456 trees hosting 123 monkeys

    That is - the order of arguments is always the same, but your translated message content has the placeholders transposed for non English languages.
