RoadRunner offers the capability to set and manage environment variables for workers. This capability allows you to set specific environment variables when workers are initialized, providing a flexible and organized method for managing application configurations.
You can set environment variables for PHP workers by defining them in the
server.env section of the RoadRunner
configuration file. These variables will be applied to all workers when they are started by the server.
Here's an example:
server: command: "php worker.php" env: DEBUG: true
In this example, when RoadRunner starts a PHP worker, it will set the
DEBUG environment variable to
All environment variable keys will be automatically converted to uppercase.
RoadRunner comes with a set of default environment (ENV) values that facilitate proper communication between the PHP process and the server. These values are automatically available to workers and can be used to configure and manage various aspects of the worker's operation.
Here's a list of the default ENV values provided by RoadRunner:
|RR_MODE||Identifies what mode worker should work with (
|RR_RPC||Contains RPC connection address when enabled.|
|RR_VERSION||RoadRunner version started the PHP worker (minimum
These default environment values can be used within your PHP worker to configure various settings and adapt the worker's behavior according to the specific requirements of your application.
