$tc = new testClass();

$tc->arr = array();

here you store an empty array in the $vars member array, under the key 
'arr' (due to your magic methods). is that what you intended?

$tc->arr['a'] = 'A';
$tc->arr['b'] = 'B';

now you are adding elements to this array under the 'arr' key in the 
$vars member array.

if (isset($tc->arr['b'])) {
    unset($tc->arr['b']);
}

you just removed b from the array under 'arr' in the $vars member array.

//var_dump is only to see results of above
var_dump($tc);

this should show something equiv. to:

array(
        'arr'   => array(
                'a' => 'A'
        )
)

what does it actually show?
