PHP Downloading a Huge Movie File (500 MB) with cURL
I wouldn't recommend serving large binary files using PHP or any other scripting technology for that matter. They where never design for this -- you can use apache, nginx or whatever standard http server you have on the back end. If you still need to use PHP, then you should probably check out readfile_chunked.
http://php.net/readfile#48683and here's a great tutorial.http://teddy.fr/blog/how-serve-big-files-through-php
good luck.
readfile() doesnt buffer. However, php itself might buffer. Turn buffering off
while (ob_get_level()) ob_end_clean();readfile($file);Your web server might buffer. Turn that off too. How you do it depends on the webserver, and why its buffering.
I see two problem that can happen:
- First: Your web server may be closed the connection by timeout. you should look the web server config.
- Second: Timeout with curl. I recommend to see this post.
