inherit that class with a new class and there you will have an access to the protected property of the class — Mladen B.

If a property is protected, it means the developer of the class doesn't want you to be able to freely directly access or modify its value from the public context.

If you analyze the class definition for this object, you will most likely find a method that will give you access to the value, for example it could be:

$obj->getId();

What if key has a dollar sign? How do I access then....Obviously $obj->get{'$t'}(); has failed.

This is not an array, it is an object.

You will need to implement a public accessor, also known as a getter to access the object property.

class context_course 
{
  public function getId()
  {
    return $this->_id;
  }
}
