How to get data from many to many fields in Symfony and how to implement it?

Question

symfony

There are vacancies and for them I get data that is many to many with the help of another request and save it to the array of the current vacancy.

if ($vacancies) {
            $ids = array_column((array)$vacancies, 'id');
            foreach($vacancies as &$vacancy) {
                $vacancy['skills'] = $this->getRowsById($this->skillRepository->getSkillsByVacancyIds($ids), $vacancy['id']);
                $vacancy['cities'] = $this->getRowsById($this->cityRepository->getCitiesByVacancyIds($ids), $vacancy['id'], 'name_' . $GLOBALS['request']->getLocale());
            }
        }

Then, through the usual foreach, you access the necessary elements to the property with ManyToMany.
