PHP files being downloaded on condition

[Samael]

Thanks for the suggestions, I will check how can I improve my
configuration upon them. Unfortunately, they seem to be less generic (ie
including specific paths) and so promote the probability of making
errors.

I'm wondering about the regex usage in location though - this is one of
the things I like very much about nginx. Can you please elaborate the
reasons for avoiding them?
