Accessing StdClass value with colon :protected

Question

How do I access the value of stdClass with colon \":protected\"?

For example, I had this $obj with these result :

object(Google_Service_Plus_PeopleFeed)         


        

Answer 1

It's not a stdClass object, it's an object of the class Google_Service_Plus_PeopleFeed. You cannot access protected properties of a class [easily]. If the class doesn't want you to access the data, then you shouldn't. But typically the class offers some method you can call to get the data, like $obj->getData() or some such. Look at the class definition or its documentation to see how you're supposed to use the class.

Answer 2

Well, I can finally access it with :

$kind = $obj['data']['items'][0]['kinds'];

Anybody can explain why? Just curious why it needs to be protected >.<

Answer 3

You can't access to a protected property from outside this object. Look at http://www.php.net/manual/en/language.oop5.visibility.php

Answer 4

Please note that there is probably a reason that these properties are protected, so you should think twice before trying to access them.

If you need to access protected variables, you could use Reflection, but there might be an easier solution. By binding a closure to the object, you should be able to access the protected variables from the closure:

class X {
   protected $a = 10;
   public $b = 20; 
}


$closure = function() {
          return get_object_vars($this);
};

$result = Closure::bind($closure, new X(), 'X');
var_dump($result());
