hi...
i found a bug in the serializer-function (current cvs 4.2.0-dev) which results in
invalid serialised-strings. if you serialize an object which uses __sleep() to define
the classnamevariables should be serialized, and some of this variables aren't
initialized (isset()==flase),
the serializer won't serialize these vars (OK). BUT he produces invalid strings
because he doesn't use the correct value for the "number of object-attributes".
O:1:"a":3:{s:5:"value";s:1:"a";}
^ ^
3 parts are predicted.. but only 1 is provided. :(
an example-script:
<?php
class a {
function a() {
$this->value="a";
}
function __sleep() {
return(array('a','b','value'));
}
}
$a=new a();
echo serialize($a);
?>
ok.. now.. i found two differend patches:
the first (not my favourite) simply serializes uninitialized variables if they had
bool(false) as value.

the second (my favourite) just puts the correct value for number of psrts in the
result:
