public static function __get($value)
No, it is not possible.
Quoting the manual page of __get :
Member overloading only works in object context. These magic methods will not be triggered in static context. Therefore these methods can not be declared static.
In PHP 5.3,
__callStatic has been added ; but there is no
__setStatic yet ; even if the idea of having/coding them often comes back on the php internals@ mailling-list.
There is even a Request for Comments: Static classes for PHP
But, still, not implemented (yet ? )
