WP_User::has_cap() public WP 2.0.0

Returns whether the user has the specified capability.

This function also accepts an ID of an object to check against if the capability is a meta capability. 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->has_cap( 'edit_posts' );
$user->has_cap( 'edit_post', $post->ID );
$user->has_cap( 'edit_post_meta', $post->ID, $meta_key );

While checking against a role in place of a capability is supported in part, this practice is discouraged as it may produce unreliable results.
