Any ideas? Yeah, you'll have to run through a foreach on the array, line by line with fputcsv. Let me know if that doesn't make sense and I'll add another example. I just outputted to a new window that downloads the file and it works fine. 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.

I have a MB file that I want to give to a user via download. However, since we want the user to only download this file once, we are doing this:. However, this means that the whole file has to be loaded in memory, which usually doesn't work. How can we stream this file to them, at some kb per chunk?
Use fpassthru. As the name suggests, it doesn't read the entire file into memory prior to sending it, rather it outputs it straight to the client. Modified from the example in the manual :.
If you would rather stream the content directly to the browser rather than a download and if the content type is supported by the browser, such as video, audio, pdf etc then remove the Content-Disposition header. Take a look at the example from the manual page of fsockopen :.
This will connect to www. You may want to make it more than bytes. I ran into this problem as well using readfile to force a download. The memory problem lies not within readfile, rather with ouput buffering. How are we doing? Please help us improve Stack Overflow. Take our short survey.
