How to set a folder size limit in Ubuntu?

Question

PHP

There is ubuntu 14.04 - a bunch of nginx + php + mysql server. There are several sites in the usr/share/nginx folder, each site in its own folder (All Sites on WordPress).
Is it possible to put a limit (quota) on the site folder, for example, 500mb. If the folder is more than 500mb, then the WordPress server would give an error. If possible, please tell me how to do it! Thanks in advance!

dd if=/dev/zero of=/foobar.fs bs=1M count=500
mkfs /foobar.fs
mkdir /foobar
mount /foobar.fs /foobar
