Subject: [PHP-DEV] Intl extension class MessageFormatter
instantiation returns NULL

Hello,

I am trying to use ChoiceFormat in the Intl extension. When I
try to do something like:

$r = new MessageFormatter("en", "There are {0?are no files|1?is one
file|1<are many files} ok");
// $r is NULL

This may be a incorrect use, but my thought is that
regardless null should not be returned because no error code
or error message can be returned. I also can not think of a
single case off the top of my head when new does not return a
object (aside from a exception being thrown on instantiation).

I am struggling to find documentation on plural usage. There
is no "ChoiceFormatter" class so it is my assumption that
message formatter parses that format. I would very much
appreciate if someone was able to point me in the right
direction. My apologies if this may have been better suited
on PECL list, but subscribing appears down and I am hastily
in search for a answer.

Try...

$fmt = MessageFormatter::create('en_GB', 'There are {0,choice,0#are no
files|1#is one file|1<are many files} ok');

echo $fmt->format(array(0)), "\n";
echo $fmt->format(array(1)), "\n";
echo $fmt->format(array(10101)), "\n";

Best place for documentation is tests, or example code I find.

What's the point of using i18n code for basic "zero, one and many"
decision. Your sample text does not have numbers and does not use plural
forms. If that function can handle plural forms, then it should know
formating rules based on language set in first argument and second
argument should only set array of strings formated according to language
rules. Second argument should not have to evaluate number every time
translator wants to use plural form.
