How WordPress can list users with specific capabilities

Question

Is there a way to list only the users that has a specific capability, such us "publish_posts" ?

Answer 1

You can just retrieve all users. Then loop through them in a foreach. Check if the user has a specific capability then push the users to another array and use that array to list them.

$all_users = get_users();
$specific_users = array();

foreach($all_users as $user){

    if($user->has_cap('specific_capability')){
        $specific_users[] = $user;
    }

}

NOTE: It seemed a nice quick and dirty solution at the time, but now I would recommend writing a query. I do not have the time to investigate this for you, so if the one downvoting this would be so kind to answer this question instead of downvoting an answer which was an actual help to the inquirer, that would be nice.
