Question

I’m new to php so the question is dump. Take a look at the following code

class A {
    private $obj;

    public function A() {
        $this->obj = new Obj();
        //$this->obj->fff() works here;
        //still var_dump($this->obj) prints NULL here
    }

    public f() {
        //$this->obj is NULL here!!!
        //$this->obj->ff() throws an error
    }
}

UPD in f() I get Fatal error: Call to a member function ff() on a non-object in ...

how should I init $obj to see it in f()?

Thank you in advance!!

Answer 1

Try the following:

public function __construct() {
     $this->obj = new Obj();
}

I think the problem is you missed function. I am not really a PHP guy but I think public function A() will work too, but the __construct is preferred.

Edit: Now you added function. I am not really sure if my answer will help you then.
