PHP files not getting executed

Hi everyone.

I’m trying to build a container for nginx and php. The nginx is working fine but I can’t execute php files. And I don’t know how to fix this.
This is my docker-compose.yml file

version: '2'
services:
 web:
  build: ./nginx
  ports:
   - "8080:80"
  volumes:
   - ./www:/usr/share/nginx/html:rw
  links:
   - php

php:
 image: php:latest
 ports:
  - "9000:9000"
 volumes:
  - ./www:/usr/share/nginx/html:rw

nginx.conf file

user  nginx;
worker_processes  1;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

What am I doing wrong?

Thank you!
