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:"^@object_container^@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(). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26737&edit=1
