Please implement magic method __isset($var) and try again. You'll see it
works fine this way.
Did a little test :
class test {
private $a;
private $b = 'foo';
public function __get($var) {
echo "__get($var)\n";
return $this->$var;
}
public function __isset($var) {
echo "__isset($var)\n";
return isset($this->$var);
}
}
$t = new test();
var_dump($t->a, empty($t->a));
var_dump($t->b, empty($t->b));
Output :
__get(a)
__isset(a)
NULL
bool(true)
__get(b)
__isset(b)
__get(b)
string(3) "foo"
bool(false)
