    The get_author_user_ids() function in WordPress is a handy tool when you want to retrieve a list of all the user IDs that are registered as authors on a WordPress site. Here's a detailed explanation of its function and a sample usage:

    Function: get_author_user_ids()

    Syntax:

    get_author_user_ids(): array
    

    Description:

    This function is used to get all the user IDs of the authors on a WordPress site. It's particularly useful in scenarios where you need to perform operations or display information related to all authors.

    Return Value:

    • Type: array
    • Description: The function returns an array containing the user IDs of all authors.

    Note:

    • The function specifically returns the IDs of users who have the capability to author posts. Depending on your WordPress configuration, this might include users with roles other than just "Author".
    • The returned user IDs can be used to fetch more detailed information about each author using other WordPress functions.

    Sample Usage:

    Here's an example of how you might use get_author_user_ids() in a WordPress theme or plugin:

    // Fetch all author user IDs
    $author_ids = get_author_user_ids();
    
    // Check if there are any authors
    if (!empty($author_ids)) {
        echo "<ul>";
    
        // Loop through each author ID
        foreach ($author_ids as $author_id) {
            // Fetch user data by user ID
            $user_info = get_userdata($author_id);
    
            // Display the author's name
            echo "<li>" . esc_html($user_info->display_name) . "</li>";
        }
    
        echo "</ul>";
    } else {
        echo "No authors found.";
    }
    

    In this example, the get_author_user_ids() function is used to get an array of author IDs. We then loop through these IDs, use get_userdata() to fetch information about each author, and display their names in an unordered list.

    This function is a simple yet powerful tool for managing and displaying author data on your WordPress site.
