This is how you can delete all entites from a entity reposiotry in symfony using doctrine (not ignoring foreign key checks). The functions returns the count of the deleted entites.

/**
 * @return int
 */
public function deleteAll(): int
{
    $qb = $this->createQueryBuilder('t');

    $qb->delete();

    return $qb->getQuery()->getSingleScalarResult() ?? 0;
}
