json_encode not working with a html string as value

Question

I am debugging this ajax for quite a time now. I have this on my jQUery file:

$(\"#typeForm\").ajaxForm({
    success : function(html){
        alert(html);

JSON doesn't play well with string output that comes out of magic method __toString() - it nearly impossible to json_encode() anything that even remotely touched something like this.

str = $str;
  }
  public function __toString() {
    return $this->str;
  }
}

$test = new Nightmare('Hello Friends.');
echo $test;
> Hello Friends.

// cooool, so let's JSON the hell out of it, EASY

echo json_encode(['our_hello' => $test]);
// This what you expect to get, right?
> {"our_hello":"Hello Friends."}

// HAHA NO!!!
// THIS IS WHAT YOU GET:
> {"our_hello":{}}


// and this is why is that:

var_dump($test);
object(Nightmare)#1 (1) {
  ["str":protected]=>
  string(14) "Hello Friends."
}

print_r($test);
Nightmare Object
(
    [str:protected] => Hello Friends.
)
