use yii\helpers\Inflector; echo Inflector::pluralize('car'); // returns 'cars' echo Inflector::pluralize('person'); // returns 'people'In the above code, the "use" statement is importing the Inflector class from the Yii helpers library. The pluralize() method is then called on the Inflector class, passing in the singular word as a parameter. This library is part of the Yii framework, a popular PHP web application framework.
