NGINX is a web server with excellent performance and low memory footprint. NGINX can also be used as a reverse proxy (FastCGI, Apache, uWSGI), as a proxy for mail protocols (IMAP, POP3) and as a load balancer.
In this post we will install NGINX as a FastCGI proxy then the PHP requests will be redirected to a PHP-FPM server.

On December 1, 2016 the PHP development community released version 7.1, which added 12 new features , we mention some of them below:
– Nullable types: Type declarations for parameters and return values can now be marked as nullable by prefixing the type name with a question mark. This signifies that as well as the specified type, NULL can be passed as an argument, or returned as a value, respectively.
– Void functions: The void type functions should not return any value so they should use an empty return or omit it completely, I think that if you omit the return it gives more clarity to the code since it is more consistent with the definition of void, the NULL value is not a valid return value for void functions.
– Symmetric array destructuring : The shorthand array syntax ([]) may now be used to destructure arrays for assignments (including within foreach).
