How does the CI framework pass parameters to a constructor in a custom class through $this->load->library?

class blog_lib{  var $CI;  var $posts_path;  var $file_ext='.md';  var $_all_posts;  var $_all_tags;  var $_all_pockets;    public function __construct($pathselect)    {    if (!isset($this->CI))    {        $this->CI =& get_instance();    }    $this->posts_path = FCPATH.$pathselect;    }

Controller:

public function index(){  $this->load->library('blog_lib');$data['config'] = $this->blog_config;$this->load->library('twig_lib');    $data['all_tags'] = $this->blog_lib->get_posts_tags();    $data['posts'] = $this->blog_lib->get_posts();$this->twig_lib->render("index.html",$data); }

How do I pass arguments to the constructor?

How do I pass arguments to the constructor?

A CI is a parameter that can be passed to a class's constructor, but must be an array when the constructor accepts arguments:

class blog_lib{    ...    public function __construct($param){        ...        $this->posts_path = FCPATH.$param['pathselect'];    }    ...}

Controller Inside:

$this->load->library('blog_lib',array('pathselect'=> 'xx'));

If you think this way is not good can be in another way, is in the CI's custom class to make a virtual empty class, and then after the empty class to define a real class, by config/autoload.php automatically load this class, you can new, then how to pass all can.
application/library/blog.php:

//虚拟类class blog{}// 真实类class blog_lib {    ....}

config/autoload.php

$autoload['libraries'] = array('blog');

Controller Inside:

$oblog = new blog_lib($value);
