The formatter object
Example #1 msgfmt_create() example
<?php
$fmt = msgfmt_create("en_US", "{0,number,integer} monkeys on {1,number,integer} trees make {2,number} monkeys per tree");
echo msgfmt_format($fmt, array(4560, 123, 4560/123));
$fmt = msgfmt_create("de", "{0,number,integer} Affen auf {1,number,integer} B?umen sind {2,number} Affen pro Baum");
echo msgfmt_format($fmt, array(4560, 123, 4560/123));
?>
Example #2 OO example
<?php
$fmt = new MessageFormatter("en_US", "{0,number,integer} monkeys on {1,number,integer} trees make {2,number} monkeys per tree");
echo $fmt->format(array(4560, 123, 4560/123));
$fmt = new MessageFormatter("de", "{0,number,integer} Affen auf {1,number,integer} B?umen sind {2,number} Affen pro Baum");
echo $fmt->format(array(4560, 123, 4560/123));
?>
以上例程会输出：
4,560 monkeys on 123 trees make 37.073 monkeys per tree 4.560 Affen auf 123 B?umen sind 37,073 Affen pro Baum
