Description:
------------
Some on can explain me that: 

<? 
class B { 
public $v; 
} 

class A { 
private $v; 
} 

$a= new A(); 
$b= new B(); 

$sa1= 'O:1:"A":1:{s:4:"Av";N;}';//Text of serialized A 
$sb1= 'O:1:"B":1:{s:1:"v";N;}';//Text of serialized B 

$a1= unserialize($sa1); 
$b1= unserialize($sb1); 

print_r($a1);//Weird 
print_r($b1);//ok B Object ( [v] => ) 

$sa= serialize($a); 
$sb= serialize($b); 

$a= unserialize($sa); 
$b= unserialize($sb); 
print_r($a);//ok A Object ( [v:private] => ) 
print_r($b);//ok B Object ( [v] => ) 
?> 

If I serialise object with private member I'm unable unserialise it! 



Reproduce code:
---------------
<? 
class B { 
public $v; 
} 

class A { 
private $v; 
} 

$a= new A(); 
$b= new B(); 

$sa1= 'O:1:"A":1:{s:4:"Av";N;}';//Text of serialized A 
$sb1= 'O:1:"B":1:{s:1:"v";N;}';//Text of serialized B 

$a1= unserialize($sa1); 
$b1= unserialize($sb1); 

print_r($a1);//Weird 
print_r($b1);//ok B Object ( [v] => ) 

$sa= serialize($a); 
$sb= serialize($b); 

$a= unserialize($sa); 
$b= unserialize($sb); 
print_r($a);//ok A Object ( [v:private] => ) 
print_r($b);//ok B Object ( [v] => ) 
?> 


Expected result:
----------------
The print of the A unserialize

Actual result:
--------------
nothing

You did not copy the serialized data correctly. It contains NUL chars!

The following shows it:
'O:1:"A":1:{s:4:"Av";N;}'
..............^ length of property name

It says length is 4 but you only gave 2 chars.

I know for the lenght it's the weird problem, it's the goof result of the serialize and not an error of copy/paste
