You should use ReflectionClass to avoid any execution or behaviours you have in\on this model. Read more aboit ReflectionClass to get more info about class\model we checking. http://php.net/manual/en/class.reflectionclass.php

foreach ($this->modelNamespaces as $namespace) {
    $reflectionClass = new \ReflectionClass($namespace);

    if ($reflectionClass->implementsInterface('common\models\FieldsInCollectionInterface')) {
        // class is implemented by FieldsInCollectionInterface
    }
}
