Use php to allow deny file download

If the range is not valid, you must output. Do not try to guess or fix the range s as it may result in corrupted downloads, which are more dangerous than failed ones. Many developers forget to send the code or the Accept-Ranges. Yet others forget that when you send a range, the Content-Length must match the length of the range rather than the size of the whole file.

You can output the file using the method described above, skipping until the start of the range and delivering the length of the range. I did my best to provide only accurate information. It would be truly sad for me if an article about avoiding common PHP errors contained errors itself.

Regardless, my point stands: PHP makes it easy to hack together code that appears to be working, but developers should read and adhere to the official specifications. Great post. Im having issues though. Im trying to get the remote files with using headers but it kills the ability for the user to be able to stream the podcast. BTW I found this post that was exactly what i needed and works great! It sends a bogus error if the range is not accepted and sends the full file size as the content length rather than just the length of the range.

Now, browsers are probably coded to cope with all sorts of errors, but we should strive to write correct code, not just working code. This method works for now and I plane to develop a better functioning version of this. Share on facebook. Share on twitter. Share on linkedin. Add a comment. Active Oldest Votes.
