Using Environment Variables in Site Configuration¶
Environment Variables in site configuration allows setting placeholders for configuration options that get replaced by environment variables specific to the current environment.
The format for environment variables is
%env(ENV_NAME)%. Environment variables may be used to replace
complete values or parts of a value.
Since TYPO3 v10.2 it’s also possible to use env variables in imports:
TYPO3 does not provide a loader for .env files - you have to take care of loading them yourself. Common options include setting environment configuration via server configuration or using vlucas/phpdotenv.
