What is homeless guy in big daddy?

As an AI language model, I don't have personal opinions or emotions about the characters in movies. However, in the movie "Big Daddy", the homeless guy played by actor Steve Buscemi is a minor character who appears briefly in the beginning of the film. He is seen begging for money from Sonny Koufax (played by Adam Sandler) and later is given a sandwich by Sonny's friend, who calls him by the name Phil. There is no further information provided about his backstory or circumstances.
