CodeIgniter: Class constructer activated on library load? - php

Question

When I load a library in CI controller the class constructor is activated automatically, even if I didn't create an object just yet.
This is weird. can this be fixed via config or something? didn't find anything on the web.
My Controller:
defined('BASEPATH') OR exit('No direct script access allowed');
class Welcome extends CI_Controller {
public function index()
{
$this->load->library('users',false);
$user = new Users();
$this->load->model('welcome_model');
$this->load->view('welcome_message');
}
}
My Class:
defined('BASEPATH') OR exit('No direct script access allowed');
class Users {
public function __construct($uname, $fname, $lname) {
print "Hello World!";
}
public function some_method() {
}
}
The code will output "Hello World" twice.

$this->load->library('myLib'); instanciate the library, so you don't need to use the new keyword.
$params_for_the_constructor = array(
'id' => 1,
'firstname' => 'Jemmy',
'lastname' => 'Neutron'
);
$this->load->library('users', $params_for_the_constructor);
$this->users->some_method();
class Users {
private $id;
private $firstname;
private $lastname;
public function __construct(array $params = array()) {
if (count($params) > 0) {
$this->initialize($params);
}
log_message('debug', "Users Class Initialized");
}
public function some_method() {
}
public function initialize(array $params = array()) {
if (count($params) > 0) {
foreach($params as $key => $val) {
if (isset($this->{$key}))
$this->{$key} = $val;
}
}
return $this;
}
}

Answer 2

in Codeigniter when you call library or call helper or call a controller or a model or anything of these its just equivalent to the new key word.
i mean if you want to make a new object of user you just do the following.
just store the instance of your first user in a varaible.
//creating first instance
$user = $this->load->library('users', $first_user_parameters);
//creating second instance
$user2 = $this->load->library('users', $second_user_parameters);
// $this->load->library('users', $param) === $user = new User($param);
in codeigniter they convert the load to new keyword by the ci_loader
