Hey guys, I'm looking for a PHP script.
A simple download manager script that basically has these features.

>> That can limit the speed of the transfer.
>> That can hide the real links
>> Disabling downloading from download managers (multiple connections)

And optional, after a certain # of downloads per day, it will stop allowing people from downloading.

I searched a lot of places like hotscripts, but there are literally hundreds of download scripts that it gets confusing..

Well, you know, this is NOT a simple script. Mainly because sending files through php is the worst idea ever. Why are you trying to make the scripting language do the work of specialized webserver? There are several apache modules that can limit bandwidth according to different conditions (e.g. send large files slower than small ones), deny multiple connections from the single IP and so on.

As of hiding real links: expand your understanding of "hiding real links". I as a user don't bother at all whether I download the file from /hardporn.avi or from /files/secretdownloads/jklssdhfjsdhfjkfhdsjkfsd/file.avi if it is still accessible in any way.

Well, I am on a shared host so I don't know if I can install apache modules.

If you are on shared host you won't be able to run the described script anyway. That script will put down the whole server and you will get your azz kicked by your hoster.
