readfile - large files

[illustrationism]

It seems that readfile does not like files that are above a certain size.

I tried to chunk the file into smaller chunks, but I got the same result: a 0 byte file downloading.

Does anyone know what the deal is? Is there something in the php.ini file that i need to change, or another method I ought to use?

Thanks,
David

My guess is that you are overloading the output buffer. Whatever method you are using to output "chunks" may need a [man]flush/man after each chunk. Or you might want to take a look at this user note on the readfile() page.
