protect flash file (.swf) with PHP3

I have developed a flash file (Macromedia Flash 4) and I put at the server. But this flash file can't be downloaded by people (read,copy), unless he/she had registerd the user member.
So anyone know how to write PHP code to protect the flash file. Thank you.

>>But this flash file can't be downloaded by people (read,copy)
If this flash file is visible on your page, it's downloadable no matter where you hide it.

What you can do is to make a preview using GIF animation or whatever, then make a link to download your *.swf file.

Wait a minute, do you know what is the difference between SWF file and FLA file?

err, how do you know if they have logged in/registered ?
if you are running sessions or place a cookie on them then just have an if () stmt in your page that checks to see if they are a member, if so, they can download/see the link whatever if not, they dont even know its there

cheers

for example
i put my happy.swf at path "www.happy.com/flash/myfile/"

if a user browse the file:"www.happy.com/flash/myfile/happy.swf"

then this person know the path, sure he can download it.

So it is no secure...

what I do is I got a table to keep user name and password. then if people login, then set cookie. So I am going to protect this file.

so how I going to do, thank you

>>then this person know the path, sure he can download it.

You can simply use htaccess+htpasswd to protect just your 'myfile' directory.
