    Return Value

    The function mostly returns string values, but it might return an empty string depending on the site configuration and the requested information.

    Sample Usage

    $site_name = get_bloginfo( 'name' );
    // Get the WordPress version
    $wp_version = get_bloginfo( 'version' );
    // Retrieve the URL of the active theme's stylesheet
