It's more of a thought experiment than anything else. The idea is to
be able to define variables in classes on the fly with method
overloading. (function __get etc.)
So something like...
class foo
{
public var $bar;
private var $_vars = array();
public function __get($var)
{
$varname = get_variable_name($var); //Whatever code I need here
$_vars[$varname] = $var;
}
}
Note I just made that up off the top of my head and it's not finished
and doesn't let you work with variables that have already been
defined.
Really I'm just trying to do it to see if I can. ;)
