user_can( int|WP_User $user, string $capability, mixed $args ): bool
Returns whether a particular user has the specified capability.
Description

Meta capabilities such as edit_post and edit_user are capabilities used by the map_meta_cap() function to map to primitive capabilities that a user or role has, such as edit_posts and edit_others_posts.
Example usage:
user_can( $user->ID, 'edit_posts' );
user_can( $user->ID, 'edit_post', $post->ID );
user_can( $user->ID, 'edit_post_meta', $post->ID, $meta_key );Parameters
