WP‐CLI

WP-CLI is the command-line interface for WordPress, allowing users to manage their WordPress installations directly from the terminal. W3 Total Cache is a popular WordPress caching plugin designed to improve website performance and reduce load times.

Integration and Usage: W3 Total Cache offers a dedicated set of WP-CLI commands for managing its functionalities, including:

Clearing Caches: The most common use case is to programmatically clear various caches (page cache, database cache, object cache, browser cache, etc.) after updates, content changes, or deployments. This can be achieved using commands like wp w3-total-cache flush.

Managing Settings: While less common for routine tasks, some W3 Total Cache settings can be managed via WP-CLI, which can be useful for automated deployments or specific configurations.

Enabling/Disabling Features: Certain W3 Total Cache features can be enabled or disabled through WP-CLI commands, offering granular control.
