PHP path info does not work about nginxconfig.io HOT 8 CLOSED

Also with path info, this line try_files $uri =404; on top of php_fastcgi.conf does not work because $uri may not point to a real path.

from nginxconfig.io.

Alternatively to check the existence of the file

if (!-f $document_root$fastcgi_script_name) {
    return 404;
}

from nginxconfig.io.

Also this line is required in php_fastcgi.conf

fastcgi_param				PATH_INFO       $fastcgi_path_info;

from nginxconfig.io.

It works perfectly fine for me.
(Maybe you've skipped the index.php fallback?)

If you check the major PHP frameworks' nginx documentation:

• https://laravel.com/docs/5.7/deployment#nginx
• https://symfony.com/doc/current/setup/web_server_configuration.html#nginx
• https://www.yiiframework.com/doc/guide/1.1/en/quickstart.apache-nginx-config#nginx

You will see only the fastcgi_split_path_info ^(.+\.php)(/.*)$; is required, everything else is defined in the stock fastcgi_params file.

try_files $uri =404; is needed for handling a non existing php file with nginx 404 error page rather than PHP-FPM's No input file specified. message.

Also If Is Evil, nginxconfig.io does not use any if in configurations.

Now I understand your issue with try_files.
I was preparing the Magento support and there is the following URL structure for setup: /setup/index.php/navigation.
The try_files failed, so I've moved it from php_fastcgi.conf to location ~ \.php$ {}, so it can be overridden.

from nginxconfig.io.

Hmm I don't know, it seems to me that this regex \.php$ will not match e.g. /index.php/some/path/info, will it?

By the way, I encountered the problem when installing moodle.

As for the frameworks documentation, it does not uses path info, the route is passed as a query string as you can see in this line try_files $uri $uri/ /index.php?$query_string. Older PHP applications still uses index.php in the URL, which is why the part after \.php still need to be matched to support path info in the URL.

from nginxconfig.io.

Example from nginx website:

location ~ [^/]\.php(/|$) {
    fastcgi_split_path_info ^(.+?\.php)(/.*)$;
    if (!-f $document_root$fastcgi_script_name) {
        return 404;
    }

    # Mitigate https://httpoxy.org/ vulnerabilities
    fastcgi_param HTTP_PROXY "";

    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;

    # include the fastcgi_param setting
    include fastcgi_params;

    # SCRIPT_FILENAME parameter is used for PHP FPM determining
    #  the script name. If it is not set in fastcgi_params file,
    # i.e. /etc/nginx/fastcgi_params or in the parent contexts,
    # please comment off following line:
    # fastcgi_param  SCRIPT_FILENAME   $document_root$fastcgi_script_name;
}

Thanks for your inputs @char101!

I've made a lot of research in this topic and commited (c25228e) the Legacy PHP routing option.
It utilises the fastcgi_split_path_info directive and PATH_INFO param only if enabled.
