PHP readfile() and large files

Question

When using readfile() -- using PHP on Apache -- is the file immediately read into Apache\'s output buffer and the PHP script execution completed, or does the PHP script exec

Answer 1

Under Apache, there is a nice elgant solution not involving php at all:

Just place an .htaccess config file into the folder containing the files to be offered for download with the following contents:

ForceType applicaton/octet-stream

This tells the Apache to offer all files in this folder (and all its subfolders) for download, instead of directly displaying them in the browser.
