ucfirst() won't do because it doesn't work with UTF-8. Maybe add a private method:

static private function ucfirst($str)
{
    return mb_strtoupper(mb_substr($str, 0, 1)) . mb_substr($str, 1);
}

[calcinai]

Ah right, good spotting. Should there be tests for this (all current tests pass)

[calcinai]

I hadn't actually seen that helpers file until now - would that be a more appropriate place to add it? e.g.

if (!function_exists(__NAMESPACE__ . '\mb_ucfirst'))
{
	function mb_ucfirst($str)
	{
		return upcase(mb_substr($str, 0, 1)) . mb_substr($str, 1);
	}
}

Is that naming ok?

[olvlvl]

I'd rather use a private method, or define mb_ucfirst() without namespace, that's because mb_ functions are defined in the global namespace, contrary to the helpers in that file.

Plan a done.

One last thing, please define the static method at the top of the class, after static public function get($locale = self::DEFAULT_LOCALE), and use static private rather than private static. Thanks.

[calcinai]

Ok cool, except it's not going to work because of the closure context

[olvlvl]

Should be @param string $str.

[calcinai]

Obviously not ideal having the function out there, but it seems like the cleanest way to retain PHP 5.3 compatibility.
