Why not test for the type of $name at each point of interest in the
SelectBoxOption
constructor? If you're passing a string value to the constructor it almost
has to be getting changed by the Tag constructor, right ?
class SelectBoxOption extends Tag {
function SelectBoxOption($name, $value, $selected=false) {
var_dump(is_string($name));
parent::Tag("option", $name);
var_dump(is_string($name));
..
}
