Property overloading is very slow. If you can, try to avoid it. Also important is to implement the other two magic methods:

__isset(); __unset();

If you don't want to find some common mistakes later on when using these object "attributes"

Here are some examples:

EDITED after Alex comment:

You can check yourself the differences in time between both solutions (change $REPEAT_PLEASE)

data = 'hi';
$a->data = 'bye'.$a->data;
}

echo '"NORMAL" TIME: '.(time()-$time)."\n";

class b
{
        function __set($name,$value)
        {
                $this->d[$name] = $value;
        }

        function __get($name)
        {
                return $this->d[$name];
        }
}

$time=time();

$a = new b();
for($i=0;$i<$REPEAT_PLEASE;$i++)
{
$a->data = 'hi';
//echo $a->data;
$a->data = 'bye'.$a->data;
}

echo "TIME OVERLOADING: ".(time()-$time)."\n";
