Description:
------------
The documentation lacks the information that objects with non-public properties uses a special syntax to associate that information with a property.

For protected properties, the property name is prefixed with \000, an asterisk, and \000 again.

For private properties, the property name is prefix with \000, the follows the class the property is defined in, then \000 again.

It's an important factor to keep in mind when transporting the serialized format, null-bytes or probably not easily expected in such a case.

The documentation should probably be reflected on php.net/manual/en/language.oop.serialization.php. I think it wouldn't heard if the link to object serialization one php.net/serialize could be made a bit more prominent.

In the first paragraph, I more precisely meant: "... uses a special serialization syntax ..."

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

The same rules as in converting to array applies:

"Object's private members have the class name prepended to the member name; protected members have a '*' prepended to the member name. These prepended values have null bytes on either side."
