remove class from code [closed]

Question

How can I remove the class from the following code and use it without the functions. I tried removing the functions and class and add it in functions.php but it did not work.

class someclass {

    function __construct() {    
        add_action('init', array(&$this, 'action_admin_init'));        
        add_action('admin_enqueue_scripts', array(&$this, 'action_admin_scripts_init'));      
    }

    function action_admin_scripts_init() {
        wp_localize_script( 'jquery', 'myscript', array('folder' => SCRIPT_URL) );
    }

    function action_admin_init() {
        add_filter( 'some_filter', array(&$this, 'register_some_filter') );
    }

}
