Symfony2 on NGINX, php file get downloaded - php

Question

I have a basic symfony2 app, when I try to reach the host I get a download instead of the execution of the PHP code.
This is the vhost configuration:
server {
listen 80;
server_name sandobox.dev www.sandbox.dev;
root /var/www/sandbox/web;
rewrite ^/app\.php/?(.*)$ /$1 permanent;
try_files $uri #rewriteapp;
location #rewriteapp {
rewrite ^(.*)$ /app.php/$1 last;
}
# Deny all . files
location ~ /\. {
deny all;
}
location ~ ^/(app|app_dev)\.php(/|$) {
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_index app.php;
send_timeout 1800;
fastcgi_read_timeout 1800;
#fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_pass 127.0.0.1:9001;
}
# Statics
location /(bundles|media) {
access_log off;
expires 30d;
# Font files
#if ($filename ~* ^.*?\.(eot)|(ttf)|(woff)$){
# add_header Access-Control-Allow-Origin *;
#}
try_files $uri #rewriteapp;
}
}
This is my nginx.conf file
user nginx;
worker_processes 4;
worker_cpu_affinity 01 10;
worker_rlimit_nofile 1024;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
events {
# max_clients = worker_processes * worker_connections
worker_connections 1024;
}
# Global environment variables
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
sendfile on;
tcp_nopush off;
keepalive_timeout 65;
keepalive_requests 100;
send_timeout 60;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
