Answer 1

1. After you download file you can check MIME type with mime_content_type()

2. It depends on server settings. Also remember that php has so timeout. Maybe it would be better if you use some kind of queue to do it asynchronously.

3. It would be better to use readfile() instead of fread() , readfile() won't cause memory problems.
4. It is important to turn off output buffering when downloading large files.

Note: readfile() will not present any memory issues, even when sending large files, on its own. If you encounter an out of memory error ensure that output buffering is off with ob_get_level().
