PHP

• nginx_php56 and nginx_php70: boolean if you need to preconfigure PHP (default: false)
• nginx_php##_sockets: list of sockets (see bellow)

You should see Nginx upstream module doc.

Each socket have:

• unix_socket
• host
• port
• weight
• max_fails
• fail_timeout

With default configuration, it works fine with PHP-FPM.
