TIL VScode bracket formatting for PHP

TIL how NGINX knows to look for index.html vs index.php

What happens when visitor hits /foo/bar URL?

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.

TIL the difference between single-threaded & multi-threaded architecture

For web dev, we don't need it. We're not bottle-necked by the processing power. We're instead bottlenecked by the ability to read files/databases. We can simulate multi-threading (and improve our app's performance) using async/await.
