Flush Redis from a PHP command?

We have REDIS running and WP-Rocket on this site.

We use WP All Import to sync pricing and stock. At the end of the sync run WP-Rocket is cleared using a purge cache command via a small php snippet. This happens automatically after the import finishes.

Some of the prices shown on the home page seem to be cached causing incorrect prices after a data import.

Is there a way to run the flush cache action via a php command that I could insert at the end of my import?

This would clear the redis database as defined in define(‘WP_REDIS_DATABASE’, 1 );
