Try this:

[code]
$view->a = array('foo');
var_dump($view->a); //foo is there, all fine

$view->a[] = 'bar';
var_dump($view->a); //bar is not there!
[/code]

To solve this, you need to return the __get by reference, like this:

[code]
public function &__get($name){
if (isset($this->vars[$name])) return $this->vars[$name];
else return null;
}
[/code]

It’s also advisable to overload isset and unset

[code]
public function __isset($name) {
return isset($this->vars[$name]);
}

public function __unset($name) {
unset($this->vars[$name]);
}
[/code]

Cheers!
