pdf properties

Hello, Is there anyway to retrieve the properties from a pdf file using php? When you right click on a pdf file in windows you can see the title of the file and you can change this property there also. I wrote a php page that lists all files in a certain directory. I want to be able show the actual title of the document instead of just the file name. I have searched the manual and google, everything that comes up refers to generating pdfs on the fly, not working with a already made pdf. Thanks in Adance, Jason Motes
