Bug description: unexpected __sleep() serialization behavior
Description:
------------
I have an object instance ($obj_root) that I want to
persist in a
session.
The object's class (object_container) defines the
__sleep() function, and
returns the array of member variables to be serialized.
function __sleep()
{
return array("objs");
}
The member variable 'objs' ($this->objs = array('foo');)
is not serialized as expected;
Arrays or other object-types result in null strings.
Upon comparing the serialized instance strings, I have
discovered that the string-ified names of the member
variables are very different:
serialize() without __sleep() wraps null chars around
the instance class name, followed by the member variable
name.
obj_root|O:16:"object_container":1:{s:
22:"[EMAIL PROTECTED]@objs";a:1:{s:3:"foo" ....
serialize() with __sleep() uses the plain member
variable name, and dismisses it as null.
If I use the __sleep() function and supply the member
variable name with null chars quoting the class name the
serialization works.
function __sleep()
{
return array("\0object_container\0objs");
}
Could this be a bug, or should the documentation be
updated to reflect this curious behaviour of __sleep().
