Can't understand this library

[David263]

Thank you so much for all the work you put into this library. However, I can't find the code that actually returns the file to the user, and I can't understand the example code that calls the library. I wanted to write my own simpler function, using your library to learn from, but I don't have the patience to read through all the code to understand it. I apologize for my lack of patience, but I'll look elsewhere to try to understand this "range" business. I've written a function that sends the file in chunks, but it doesn't allow the user to reposition the video and it only works on Firefox, not on Chrome, due to lack of "range".

Editorial: it is strange that some everyday operations, like doing insecure FTP, is easy to do based on just the PHP Manual, yet other operations, like doing secure FTP or providing the user with a video file, are hairy and not explained in the Manual.
