Php show page content and download file

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.

However, zip and exe files are downloaded automatically to the hard drive by default. You can force images or other kind of files to download directly to the user's hard drive using the PHP readfile function. Here we're going to create a simple image gallery that allows users to download the image files from the browser with a single mouse click.

If you see the above example code carefully, you'll find the download link pints to a "download. Also, we've used PHP urlencode function to encode the image file names so that it can be safely passed as URL parameter, because file names may contain URL unsafe characters.
