Question

I’m querying for the ID of a field by accessing a class function which someone has already put in place. The result is a object returned with protected member variables. I’m struggling to see how I can access the member variable values outside the class.

Answer 1

Just add a “get” method to the class.

class Foo
{
    protected $bar = 'Hello World!';

    public function getBar()
    {
        return $this->bar;
    }
}

$baz = new Foo();

echo $baz->getBar();
