codeigniter:如何在一个类中访问其他函数的多个变量？

Question

例如,我有一个这样的类

public function data() {
     $a = 1;
     $b = 2;
     $c = 3;
}

public function codeigniter() {
     $a, $b, $b //how i can get the value??
}

我怎样才能获得的价值$a,$b,$c这样我可以在使用它codeigniter()的功能？我用codeigniter？我需要添加return;吗？

我假设这两个函数同时在classigniter和codeigniter的控制器类中

class Sample extends CI_Controller {
// declare variables
    public $a;
    public $b;
    public $c;

    public function __construct() {
        // call codeigniter method
        $this->codeigniter();
    }

    public function data() {
        $this->a = 10;
        $this->b = 11;
        $this->c = 12;
    }

    public function codeigniter() {

        // call method data();

        $this->data();

        echo $this->a; // prints 10
        echo $this->b; // prints 11
        echo $this->c; // prints 12


    }

}
