Environment Variables

Bedrock tries to separate config from code as much as possible and environment variables are used to achieve this. The benefit is there's a single place (.env) to keep settings like database or other 3rd party credentials that aren't committed to your repository.

PHP dotenv (opens new window) is used to load the .env file. All variables are then available in your app by the built-in getenv, $_SERVER, or $_ENV methods.

However, we use the env (opens new window) library and its env function which handles simple type coercion (such as converting the string 'True' to the boolean true). We recommend you use env as well for reading environment variables.

Currently, the following env vars are required:

• WP_HOME
• WP_SITEURL

The following vars are required if DATABASE_URL is not set:

• DB_USER
• DB_NAME
• DB_PASSWORD

Note

There is also the DATABASE_URL which is optional.

WP_ENV

Although it isn't required (if not defined elsewhere, Bedrock will default to production), WP_ENV is used by several pieces of the Roots stack, as well as software outside of it, to modify behavior based on environment. There are three values you can set for WP_ENV that Bedrock will understand:

• production
• staging
• development

Make sure that these are set correctly in your different environments.
