Placeholders in language lines

How to use placeholders in 
$this->lang->line('misc_key', FALSE);

It is used in standard libraries  (e.g. from validation), but how to use it in my own libs and models?

Code:

echo sprintf($this->lang->line('somekey'),'XYZ');//load language library before use

Is this the best way?

Maybe this will help, you can use it in any library Class.

PHP Code:

// Your lang file - Created under language folder language-name
<<?php
defined('BASEPATH') OR exit('No direct script access allowed');

$lang['your key'] = "Your Message.";

// End of lang file


// Your Class
class Your_Class
{
    /**
     * @var  CI_Controller - The CI Super Object
     */
    protected $CI;

    /**
     * constructor.
     * -------------------------------------------------------------------
     *
     */
    public function __construct()
    {
        $this->CI =& get_instance();

        $this->CI->lang->load('your lang file', 'english');
    }

    /**
     * Your Method.
     * -------------------------------------------------------------------
     *
     */
    public function test()
    {
        show_error($this->CI->lang->line('your message'));
        
        // or

        echo $this->CI->lang->line('your message');
    }

} 


 
When working outside of a controller you need to get the CodeIgniter Super Object.

Also SEE: The CodeIgniter Documentation on Language files etc;
