I have converted most of my Apache HTTPd mod_rewrite rules over to nginx's HttpRewrite module (which calls PHP-FPM via FastCGI on every dynamic request). Simple rules which are defined by hard locations work fine:
location = /favicon.ico { rewrite ^(.*)$ /_core/frontend.php?type=ico&file=include__favicon last; }
I am still having trouble with regular expressions, which are parsed in mod_rewrite like this (note that I am accepting trailing slashes within the rules, as well as appending the query string to every request):
mod_rewrite
# File handler
RewriteRule ^([a-z0-9-_,+=]+)\.([a-z]+)$ _core/frontend.php?type=$2&file=$1 [QSA,L]
# Page handler
RewriteRule ^([a-z0-9-_,+=]+)$ _core/frontend.php?route=$1 [QSA,L]
RewriteRule ^([a-z0-9-_,+=]+)\/$ _core/frontend.php?route=$1 [QSA,L]
RewriteRule ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)$ _core/frontend.php?route=$1/$2 [QSA,L]
RewriteRule ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)\/$ _core/frontend.php?route=$1/$2 [QSA,L]
RewriteRule ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)$ _core/frontend.php?route=$1/$2/$3 [QSA,L]
RewriteRule ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)\/$ _core/frontend.php?route=$1/$2/$3 [QSA,L]
I have come up with the following server configuration for the site, but I am met with unmatched rules after parsing a request (eg; GET /user/auth):
attempted nginx rewrite
location / {
# File handler
rewrite ^([a-z0-9-_,+=]+)\.([a-z]+)?(.*)$ /_core/frontend.php?type=$2&file=$1&$3 break;
# Page handler
rewrite ^([a-z0-9-_,+=]+)(\/*)?(.*)$ /_core/frontend.php?route=$1&$2 break;
rewrite ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)(\/*)?(.*)$ /_core/frontend.php?route=$1/$2&$3 break;
rewrite ^([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)\/([a-z0-9-_,+=]+)(\/*)?(.*)$ /_core/frontend.php?route=$1/$2/$3&$4 break;
}
What would you suggest for dealing with my File Handler (which is just filename.ext), and my Page Handler (which is a unique route request with up to 3 properties defined by a forward slash)?
As I haven't gotten a response from this yet, I am also unsure if this will override my PHP parser which is defined with location ~ \.php {}, which is included before these rewrite rules.
Bonus points if I can solve the parsing issues without the need to use a new rule for each number of route properties.
