PHP/HTMLDOC For Creating PDF Files

Has anyone had any success in using the HTMLDOC program thru PHP to convert html files to PDF? If so, how did you call the htmldoc program in you PHP script? Since all I really want to do is create a simple raffle ticket when someone registers through the web and print it to the local server's printer the HTMLDOC program seems to be easier to use than trying to learn the pdf functions in php.
