php - Renaming files when downloading it

I want to rename file when user downloads it.

Right now, I'm sending content-disposition and content-length headers and then send file to user with fpassthru PHP function.

But there is 3 problems with this method:

  1. If I'm sending big (above 3-4Gb) files this way, then my PHP script runs too much time and may be killed by timeout.
  2. If user cancels the download, PHP script continue to read and send the file
  3. If user pauses the download, he cannot resume it later.

Is there any nicer way to rename files on download?

Since the question was asked, some time has gone by and html5 gave us a different approach to this:

<a href="someWeiredFileName.rar" download="coolFilename.rar">Download</a>

The attribute download (learn more) defines the default filename for storing the file on the clients computer (he'll still be able to change it!).

Note: this won't affect anything on your server.
