Re: [PHP5]__get, __set and isset()

Hi, Is this really a bug. I think not. There is no variable $o->a or $a->b in the class OO there is only the variable $elem and $a and $b is a member of that array So ... The fact that PHP5 provides __set and __get magic functions does not mean that the actual variables exist with that particular name in the class ? Perhaps it would be nice to have a __isset magic function ?
