Tried to trigger this at home. But it works as expected.

But: 
  1. This is a linux machine.
  2. Home compiled
  3. I'm not stressed out...
  4. The code is much cleaner.

My guess is that I screwd up with one of the '&' in some deep nested
retuen tree


As I said, this code works:
class ArrayObj implements ArrayAccess {

private $_val;
public  $valAsProp;

function __construct($val){
$this->_val = $val;
$this->valAsProp =& $this->_val;
}
//
// ArrayAccess interface
//
function  offsetExists($key)   { return isset($this->{'_'.$key});  
}
function &offsetGet($key)  { return  
$this->{'get'.ucfirst($key)}();}
function  offsetSet($key,$val) {  $this->{'_'.$key} =
$val; }
function  offsetUnset($key){  $this->{'_'.$key} =
null; }

function &__get($key)  { return   $this->{'_'.$key};   
}

function &getVal() {
return $this->_val;
}
 }

$arrayobj = new ArrayObj(new ArrayObj('an other val'));

$db = new mysqli('localhost');
$stmt = $db->prepare("SELECT ? as `val`");
//$stmt->bind_param('s', $arrayobj->valAsProp);
//$stmt->bind_param('s', $arrayobj->val);
$stmt->bind_param('s', $arrayobj['val']['val']);
$stmt->execute();
$stmt->bind_result($res);
$stmt->fetch();
$stmt->close();

echo "\n$res\n";

?>

Description:

Fatal error: Objects used as arrays in post/pre increment/decrement
must return values by reference

when I try to use
$mysqli_stmt->bind_param('s',$arrayAccessObj['offset']);

even though offsetget is declared as

function &offsetGet($key) {
return $this->{'_'.strtolower($key)};
}
