Catch-all should pass path to index.php in nginx - php

Question

In apache I have an .htaccess that will rewrite from http://server/api/any/path/i/want to http://server/api/index.php if no file or folder is found.
Options -MultiViews
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $0#%{REQUEST_URI} ([^#]*)#(.*)\1$
RewriteRule ^.*$ %2index.php [L,NC,QSA]
</IfModule>
I'm moving to docker and will use nginx instead and I want to re-write the rewrite.
Important to note is that using apacheand .htaccess $_SERVER['REQUEST_URI'] is /api/any/path/i/want and not the re-written url (index.php....).
I'm not that well versed with nginx but from posts on SO I've figured some things out.
Relevant section of site.conf
location / {
root /app/html;
try_files $uri $uri/ index.html /index.php?$args;
}
location ~ \.php$ {
try_files $uri #missing;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass php:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
location #missing {
rewrite ^ $scheme://$host/api/index.php permanent;
}
The above config will unfortunately only redirect to index.php and is as far I've managed to get.
How can I do the same thing in nginx?

Answer 1

This is a typical nginx configuration for PHP-FPM.
server {
root /app/html;
location / {
try_files $uri $uri/ /api/index.php$is_args$args;
}
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass php:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
Notice the differences from your example:
Removed the unnecessary #missing location block.
Removed the try_files statement from the .php location block.
Moved the root declaration to the server block. If you need to have different roots, please specify this in your question.
The only try_files statement includes the full path for your api/index.php.
If a request comes for a non-existing path, it will be handled by your /app/html/api/index.php script, acting as a global entry-point.
