TIL php-fpm

PHP runs as a separated service when using PHP-FPM. By using this PHP version as language interpreter, requests are processed through a TCP/IP socket; so that the Nginx web server only handles the HTTP requests and PHP-FPM interprets the PHP code. The fact of having two separate services is key for increasing efficiency.
