it's due to print_r specific behavior for object's properties... 

if you use var_dump instead, you will see it's not trimmed.

Thanks, var_dump() works. But it would be great if get_object_vars() and foreach() could be fixed.

Here is a more detailed test:

$arr = ["abc\0def" => "abc\0def"];
$obj = (object)$arr;

print_r($arr); // ok
echo "\n";
var_dump($obj); // ok
echo "\n";
echo serialize($obj); // ok
echo "\n";
echo (int)property_exists($obj, "abc"); // ok
echo "\n";
echo (int)isset($obj->{"abc"}); // ok
echo "\n";
echo json_encode($obj); // ok
echo "\n";
var_dump((array)$obj); // ok
echo "\n";

var_export($obj); // bug
echo "\n";
print_r($obj); // bug
echo "\n";
debug_zval_dump($obj); // bug
echo "\n";
var_dump(get_object_vars($obj)); // bug
echo "\n";
echo get_object_vars($obj)["abc"]; // bug
echo "\n";
foreach ($obj as $key=>$val) {
  echo $key." : ".$val."\n"; // bug
}

Windows snapshots are currently not available, so I tried php5.5-201301151230 on Ubuntu and it works, thanks a lot!
