How to download large files using php

I tried some chunk based codes that I found in Google, but the file always was delivered corrupted. Probably because of bad code. There are some ideas over in this thread. I don't know if the readfile method will save memory, but it sounds promising. If so, each Apache process handling this will end up growing to the size of this file, as that data will be cached. Try pass to this function not the content of file only it's path.

Next send all headers once and after that read part of this file using fread , echo that chunk, call flush and repeat.

If any other header will be send in the meantime then finally transfer will be corrupted. Symlink the big file to your document root assuming its not an authorized only file , then let Apache handle it. That way you can accept byte ranges as well.

MiPony - The program supports hundreds of file hosting services and extra features just like JDownloader does.

PyLoad - The program does not support as many hosters as JDownloader or MiPony, but it may make up for it in other ways. It has been designed with low hardware requirements in mind, and while it makes sure of that, it does not sacrifice core functionality for it. With that said, it is difficult to set up as you need to run a configuration script first on the command line and run a core program first before you can connect clients to it.

There is no definitive answer to that question. It depends on what you require more than anything else.

Not sure why this is not accepted. Another unnecessary implementation. See my comments on stackoverflow. That is incorrect. I know it by experience. Key is that readfile doesn't allow files close to or larger than the PHP memory limit to be downloaded. This is a simple solution that works, and as such, you shouldn't downrate it.
