另一篇 php 相關，提到 symfony 4 的目錄結構
http://paul-m-jones.com/archives/6564
"… it might be nice if Symfony 4 adopted more existing common practices,
used by roughly 70% of Packagist packages. That is, to use config/ for
the top-level config directory, and public/ for the top-level
document-root directory"
這是目前 laravel 的標準目錄結構，原來這樣的目錄用的那麼普遍呀
是說 symfony 想要用的 /etc 跟 /web 對我來說倒是蠻親切的就是 :p
