In this article, we look at the benefits and limitations of installing WordPress in a subdirectory, how to install and manage subdirectory installs, and how to move WordPress core out of and into a subdirectory for an existing site.
One of the common criticisms PHP developers level at WordPress is that it installs all its core files directly in the web root directory. Modern PHP frameworks like Laravel install their required files as separate dependencies in a vendor directory, each residing in its own specific subdirectory. Not only that, but unlike WordPress, Laravel keeps almost all the PHP files out of a publicly accessible directory, which is very nice for security. This makes for a cleaner, more secure folder structure in the application’s web root.
These modern PHP application directory structures make a default WordPress install look decidedly unprofessional. While it’s not possible to move all the PHP files out of the public web root in a WordPress install, you can customize your installation to mimic this dependency-based development concept by installing WordPress in a subdirectory.
