Hi guys, I am new to php oop, 

I am trying get an object of sibling method inside a class, seems not working.

class Upload extends Base_controller{

 private function sql () {
    $get = Upload::all();
 }
  public function get_index() {
    dd($this->sql()->get);
  }
}

Use return values just like you would any other function.

private function sql() {
	return Upload::all();
}

public function get_index() {
	dd($this->sql()); // ???
}
