WP_User::get_role_caps()

Retrieves all of the capabilities of the user’s roles, and merges them with individual user capabilities.

Description

All of the capabilities of the user’s roles are merged with the user’s individual capabilities. This means that the user can be denied specific capabilities that their role might have, but the user is specifically denied.

Return

(bool[]) Array of key/value pairs where keys represent a capability name and boolean values represent whether the user has that capability.
