Hi there,

Having re-read the docs, I can see that the interpretation could be
made clearer. Can you suggest any wording that might have helped you
understand then, what you do now? Maybe it can become easier for the
next person ;-)

Would adding a link to
http://nginx.org/en/docs/http/request_processing.html#simple_php_site_configuration
have helped, do you think? It is an example rather than complete
documentation, and it leaves out the "^~" thing, so maybe it wouldn't
have been directly useful.

That looks reasonable. "^~" only matters if you have (top level) regex
matches -- which here, you don't.

(Avoiding top level regex matches makes it very easy to know which
location{} will match any particular request. That's usually considered
a Good Thing.)

In this case, you want different fastcgi_param lines for different php
scripts -- so repeating the common config (by using "include") and adding
the specific parts, like you have done, is probably the best way.

You're welcome.

All the best,
