WordPress How to Make a Website with WordPress WordPress Widgets and Custom Menus How to Create Widgetized Areas in WordPress

How does the %1$s and %2$s portion of create_widget() work?

I notice that this line from create_widget():

'before_widget' => '<div id="'.$id.'" class="widget %1$s %2$s">'

turns into this in the html that is served:

<div id="uptop" class="widget text-3 widget_text">

How does %1$s eventually turn into text-3 and %2$s turn into widget_text? I understand that those are related to sprintf, but that function is not being called here, correct? I'm sure it must have something to do with the internal WordPress functions, but I can't find any documentation that says how this works and browsing through the code in widgets.php has still left me clueless.

Here is the complete function for reference:

// Function for creating Widegets
function create_widget($name, $id, $description) {

    'name' => __( $name ),    
    'id' => $id,
    'description' => __( $description ),
    'before_widget' => '<div id="'.$id.'" class="widget %1$s %2$s">',
    'after_widget' => '</div>',
    'before_title' => '<h3>',
    'after_title' => '</h3>'


// Create the actual widgets
create_widget("Header", "uptop", "Displays in the header of the site, above the title");
