Description:
------------
I am requesting other magic methods for automatic type conversion of objects, 
besides __toString(), in particular, __toArray(). The default method of converting 
an object to an array is, in my opinion, rather odd, since it provides the values 
of inaccessible properties and uses weird conventions, like an asterisk for 
protected properties and prefixing the class name for private properties.

Test script:
---------------
class Example {
   protected $a, $b, $c;

   public function __construct ($a) {
      $this->a = $a;
      $this->b = 'B';
      $this->c = 'C';
   }

   public function __toArray () {
      // Only return a and b, and don't distinguish scope
      return array (
         'a' => $this->a,
         'b' => $this->b
      );
   }
}

for ($examples = array (), $i = 0; $i < 3; $examples[] = (array) new Example(++$i));
echo json_encode($examples, JSON_PRETTY_PRINT);

Expected result:
----------------
[
   {
      "a": 1,
      "b": "B"
   },
   {
      "a": 2,
      "b": "B"
   },
   {
      "a": 3,
      "b": "B"
   }
]
