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.
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();
