Answer 1

+6 A:

You can remove it right after the download. output the content of the file, then close it and unlink it.

Edit: example

$fo = fopen($f, 'rb') ;
    $content = fread($fo, filesize($f)) ;
    fclose($fo) ;
}
// Stream the file to the client 
header("Content-Type: application/octet-stream"); 
header("Content-Length: " . strlen($archive)); 
header("Content-Disposition: attachment; filename=\"myfile.exe\""); 
echo $archive;
unlink($f);

This sounds great, but how can I output the content of the file? I meant to say that the file that is to be downloaded is actually an executable (.exe) file that was the result of a C++ compilation. How can I give the user a exe file download?

Send the appropriate header `header('Content-Type: application/octet-stream');` before writing to the buffer.

QAH, what streetpc is saying is don't provide a link to the file. Instead your original script should produce the file and output it to the user with the above code. Or you can provide a link to a script such as the one above that outputs and removes the file.

Answer 2

+2 A:

Set up a cron job to to run your cleaning script every few minutes. You could use the filemtime() function to see when a file was created, and delete it if the file is considered "old enough".
