Question: What does the Phantom eat and what does he spend his salary on? Presumably he can't just go to the shops etc with his mask on. If he doesn't leave the opera house where does he learn his skills like driving a carriage, who does he practice sword fighting with? Wouldn't his health suffer if he spends decades living in this damp cold rat infested place wading through lakes all the time? He even complains about it being cold himself at one point. Surely if it snowing outside his lair can't be warm but he's not wearing much.
Answer: First, it is established in the movie that he is dependant on Madame Giry and it is presumed she does his shopping for him. As for learning skills, it is established he is a genius and one can assume he is very well read. Additionally, for single handed skills, like driving a carriage, he can possibly go out at night to learn them. As for his living conditions, the human body adapts well to continuous conditions, it is how the people in Siberia can tolerate lower temperatures better than those who live close to the equator. Lastly, one can easily assume he has other (warmer) clothes that he wears off camera.

There is a character simply known as 'the Persian' He has known the Phantom his whole life and would have taught him horse driving. In the book, the Phantom has a life before the opera house where he would have learned fencing and torture. Also, the phantom knows all the secret passages. When it's cold he leaves his lair and lives someplace warmer.
You're totally right but also, in addition to your mention of The Persian, in the book it is he that is the Phantom's only "friend" or whatever but in the movie there is no Persian exactly but the two Characters Madam Giry and The Persian from The Phantom of the Opera by Gaston L. Are both combined as one, to be know as Madame Giry in the 2004 flim.
