New Comment:
Using a transient keyword is better because if we have the following
case:
class A { $a; $b; }
class B extends A { $c function __sleep() { return array("c"); } }
now if you serialize b you will not serialize the $a and $b members
from
class A. So the sleep functions actually changes the encapsulated
behaviour of A. Or we should call the superclass A::__sleep() method
and
join that with the new arrow.
However this is much cleaner code. And wether a member is transient or
not should be declered nearby the member to keep else other developers
may not now wether the member will be serialized or not.

While it is possible to exclude members from serialization using
__sleep(), it has downsides:
- Using get_object_vars($this) to return the members is extremely slow
- Manually maintaining an array with the members is error prone and can
be quite some work
A transient keyword to exclude members from serialization would make it
easier ...

Description:
------------
PHP has no advanced support for serialization.
I think, that is problem, that PHP serialize all properties. What about
add single keyword (as transient) for property which can't be
serializable?
Example:
class Foo {
public $a;
public transient $b;
}
