PHP function to call another classes -

i have seperated few file php classes, , need them in 1 function this:

include("require-class.php");  require_multi("db-class.php", "settings.php","users-class.php");  class ajaxlogin {   private $settings;               private $users;    public function __construct(settings $settings, users $users) {     $this->settings = $settings;     $this->users = $users;     } }  global $ajaxlogin; $ajaxlogin = new ajaxlogin; 

class in settings.php named settings , 1 in users-class.php users. got error:

php catchable fatal error: argument 1 passed ajaxlogin::__construct() must instance of settings, none given, called in /var/www/html/idcms/admin/class/login-ajax.php on line 47 , defined in /var/www/html/idcms/admin/class/login-ajax.php on line 13, referer: http://localhost/idcms/admin/

your constructor of ajaxlogin requires 2 arguments: $settings , $user. need call:

$ajaxlogin = new ajaxlogin($settings, $user); 

of course need instantiate settings , user before, like:

$settings = new settings();    // add arguments if required $user = new user();            // add arguments if required 

---

update

if want instantiate settings , user inside ajaxlogin, remove arguments __construct this:

class ajaxlogin {     private $settings;               private $users;      public function __construct() {         $this->settings = new settings();         $this->users = new users();               } } 

however, first approach better 1 because uses class ajaxlogin knows class depends on settings , user. see this question more detailed answers this.
