Description:
------------
Im not sure if it is a bug or not.

with an object inside an object, this is possible:
echo $test->testobject()->color;

with and array inside an object, this is NOT possible:
echo $test->testarray()["color"];

In other words, when an object returns an array, I can not directly access it. 

This will work:
$temparray=$test->testarray();
echo $temparray["color"];


Reproduce code:
---------------
<?php
class c_testobject{
  function __construct(){
    $this->color="red";
	}
}
class c_test{
  private $testobject; private $testarray=array("color" => "red");
  function testobject(){
		$testobject=new c_testobject;
		return $testobject;
  }
  function testarray(){
    return $testarray;
  }
}
$test=new c_test();
echo $test->testobject()->color;
echo $test->testarray()["color"];
?>

Expected result:
----------------
redred

Actual result:
--------------
