The actual result of var_dump($b) is: $b = object(SplFixedArray)#2 (2) { ["0"]=> int(1) ["1"]=> int(2) } The keys are strings and not integers and this causes ------------------------------------- $b = unserialize(serialize($a)); SplFixedArray::fromArray($b->toarray()); ------------------------------------- To throw an exception 'InvalidArgumentException' with message 'array must contain only positive integer keys' ------------------------------------------------------------------------ [2011-12-19 10:31:53] digital1kk at interia dot pl Description: ------------ If SplFixedArray object is created via unserialize() of serialized instance then the getSize() and count() methods return 0 instead of expected actual size.
