The TV actor, pictured, who plays grumpy English teacher Grantly Budgen in the top BBC school drama, now set in Greenock, is headlining an evening for Dreams Come True Inverclyde.
At the Tontine Hotel later this month, Philip hopes to raise awareness of the work of the local charity, which was set up two years ago to help seriously-ill children.
Philip said: "I'm looking forward to helping the wonderful charity Dreams Come True in any way I can."
The fundraising event has been organised to highlight the forthcoming Great Wall of China trek by volunteers in aid of the charity - and it's hoped that on the night other stars from the show will join the actor to support the local charity.
The Inverclyde group is a branch of the national charity that aims to bring joy to the lives of terminally and seriously-ill children and young people across the UK.
Local Dreams Come True co-ordinator Chris Jewell said: "We are very grateful to Philip and friends for helping in this way.
"Dreams Come True truly is a wonderful charity and we want to make as many dreams come true as possible."
The special charity night takes place at the Tontine Hotel on Monday 13 August from 7.45pm for 8pm, with food provided.
Tickets for the event cost £10 and are available from Chris by calling 783000 or sending an email to email@example.com
