范例

Example #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";
?>

Example #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";
?>

以上例程会输出：

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.
