How to detect when file is downloaded completly in php?

Hi,

Does any one how we can detect when user finishes full file download?

like if i want to create a system in which user only get points when he streams full movie only not just he opens the movie from website.

Any help appreciated.

Thankx in advance

 

one way is to do an ajax check to see if the move_uploaded_file function is performed by looking at the loaction of the target file

 

I guess you should build custom movie player. However i am interested about this too
