Philip had two natural sons; one of them, Louis d'Orléans, became Bishop of Poitiers and Bishop of Beauvais. He also had a natural daughter, Marie d'Orléans, who married Gédéon V of Beauvilliers.
As a consequence of the Treaty of Brétigny, he served some time as a hostage in England for the good behavior of his brother King John II of France, when he was temporarily released.
The Duke of Orléans died in 1375 without any legitimate issue. His title and lands returned to the royal domain of France.
