Doctrine

With DoctrineBundle, the bundle registers the column type phil_opening_hours: OpeningHours in one JSON column, as phil/opening-hours's OpeningHoursArray writes them.

#[ORM\Column(type: 'phil_opening_hours', nullable: true)]
private ?OpeningHours $hours = null;

A value that is not OpeningHours is refused on writing; a stored text that is no JSON, nested more than 6 levels, or no hours, on reading.
