 New Comment:

Actually, the return values section of that page is plain wrong too. The return 
value is actually ignored completely.

Reopening; will fix up.

Serializable::unserialize() returns the unserialized object. Thus, the type is 
mixed, because the returned object can be of any class type.

void would suggest that the call to unserialize() would not return any value. 
That would be the case if the syntax for unserialize() were unserialize($string, 
&$result). But, that's not the case.

From manual page: http://www.php.net/serializable.unserialize#refsect1-serializable.unserialize-returnvalues

Serializable::unserialize() does not return "mixed", it does not return anything at \
all as one can see from the examples, because unserialize() is called instead of \
__construct(). The formal return type should then be "void".
