serialize() works not correct with cascaded objects in some circumstances (on PHP 3.0.1x this
worked correct !!) :
You have an object whitch contains "normal" variables like integers, strings and also
other objects. These other objects also contains integers, strings etc. and again objects:
object 1 --- variable 11
|- variable 12
| :
|- variable 1x
|- object 2 --- variable 21
|- variable 22
| :
|- variable 2x
|- object 3 --- variable 31
| :
|- variable 3x
Under some circumstances the output that serialize() produces does only contain the top-level object
(object 1)with its "normal" variables (variable 11 ... variable 1x). The other objects
(object 2 and 3) with all there variables are lost.
