Nginx isn’t gzipping php pages, but I don’t know why? I’m using the Audits tab in Google Chrome Developer tools to determine that the pages aren’t being gzipped.

Check your PHP output header for “Content-Type”, if it is not text/html and one of the gzip\_types, it won’t be compress. Your config I have tested on my server, it will compress normally.

Thanks for testing it MagicBear. Google Chrome reports content type header as: Content-Type:text/html; charset=UTF-8 So still not sure why it is not working. I checked nginx changelog and couldn’t see anything that looked to be pointing out that this was an issue in older versions of nginx. Still, I will try latest stable version and see if that makes any difference.

Hmm… well I installed the latest version and found that actually nothing is being zipped. Was probably the same thing before, but most of the static files have gzip versions and so were included by gzip\_static, making it look like only PHP wasn’t being zipped. Any ideas?

In fact, you can try to open php internal gzip compress function, you may find it at php.ini, change this to On zlib.output\_compression = Off and php will compress it auto before send to nginx.
