Plural forms format
Since version 1.1.6 CLDR-based plural choice format can be used with a simpler syntax
that. It is handy for languages with complex plural form rules.
The rule for English plural forms above can be written in the following way:
Yii::t('test', 'cucumber|cucumbers', 1);
Yii::t('test', 'cucumber|cucumbers', 2);
Yii::t('test', 'cucumber|cucumbers', 0);
The code above will give you:
cucumber
cucumbers
cucumbers
If you want to include number you can use the following code.
echo Yii::t('test', '{n} cucumber|{n} cucumbers', 1);
Here {n} is a special placeholder holding number passed. It will print 1 cucumber.
You can pass additional parameters:
Yii::t('test', '{username} has a cucumber|{username} has {n} cucumbers',
array(5, '{username}' => 'samdark'));
and even replace number parameter with something else:
function convertNumber($number)
{
// convert number to word
return $number;
}
Yii::t('test', '{n} cucumber|{n} cucumbers',
array(5, '{n}' => convertNumber(5)));
For Russian it will be:
