php - What is the right way to group my methods inside a single model? -

i'm sorry title, maybe couldn't describe well. here's want:

now if create model m.php , put inside models folder following code:

class m extends ci_model {    public function username() {     print "john doe";   }    public function password() {     print "abc123";   }  } 

now, can following in controller :

$this->load->model("m"); $this->m->username(); // prints john doe $this->m->password(); // prints abc123 

now need make in way on can call methds above following:

$this->m->genralinfo->username(); // prints john doe  $this->m->privacy->password(); // prints "abc123" 

how can achieve ? want in order group methods specific alltogether, helps me structure code better.

**i aware possible create new model every group of methods i'd keep related user inside single model **

is possible using single model ?

i think want this

class m extends ci_model {     public $genralinfo;     function __construct()     {         parent::__construct();         $this->genralinfo=new genralinfo();     }  } class genralinfo //class genralinfo extends ci_model//you may extend ci_model {     public function username() {         print "john doe";     }      public function password() {         print "abc123";     }  }
