Symfony2, phpbrew, nginx, php 7.1 and File not found - php

Question

I've been attempting to upgrade to php 7.1 using phpbrew, and elected to install it with nginx, as I read everywhere that it was simpler than Apache (not that simple, in my humble opinion).
As I was trying to run Symfony2 with nginx, I came across this doc page, which gives a basic config for Sf2 on nginx.
I managed to configure php-fpm to serve app_dev.php, and every file ending in .php correctly. However, as soon as I go to a different URL (/home for instance), the nginx config breaks and I get a File not found error in php-fpm.
How do I configure the nginx virtual host to allow for everything after app_dev.php or app.php to be rewritten (as it would with modrewrite on apache2)?
My nginx file for reference:
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /usr/share/nginx/html;
index index.html index.htm;
server_name localhost;
location / {
try_files $uri $uri/ =404;
}
location /my-app {
index web/app_dev.php;
try_files $uri /web/app.php$is_args$args;
}
location /dist {
root /usr/share/nginx/html;
index depp/index.php;
try_files $uri /depp/index.php$is_args$args;
}
location ~ \.php$ {
fastcgi_pass unix:/home/gabriel/.phpbrew/php/php-7.1.0/var/run/php-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
fastcgi_param REQUEST_URI $uri?$args;
}
}

You are missing a rewrite condition to catch-all the incoming requests and forward them to your front controller.
Try something like:
# strip app.php/ prefix if it is present
rewrite ^/app\.php/?(.*)$ /$1 permanent;
location /my-app {
index app.php;
try_files $uri #rewriteapp;
}
location #rewriteapp {
rewrite ^(.*)$ /app.php/$1 last;
}
# Symfony 2 app index
location ~ ^/app\.php(/|$) {
fastcgi_pass unix:/home/gabriel/.phpbrew/php/php-7.1.0/var/run/php-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
# deny access to any other php files
location ~^.*\.php(/|$) {
deny all;
}
You current configuration is a more general configuration for any .php script but Symfony2 and framework in general only provide a catch-all front-controller.
