FWIW: as of PHP 5.3.7 there is an error thrown when
$limitit->getInnerIterator() is called[1]:
| Fatal error: Uncaught exception 'LogicException' with message
| 'The object is in an invalid state as the parent constructor was
| not called' in â¦

When you actually trying to rewind the object it is making php to
segfault.
Like here:
$limitit = unserialize( serialize($limitit) );
echo $limitit->next();
var_dump($limitit->getInnerIterator());

Description:
------------
Serializing of LimitIterator doesn't work.
Reproduce code:
---------------
$it = new ArrayIterator(array('test' => 'test'));
$limitit = new LimitIterator($it, 0, 10);
var_dump($limitit);
var_dump($limitit->getInnerIterator());
$limititSer = serialize($limitit);
var_dump($limititSer);
$limitit = unserialize($limititSer);
var_dump($limitit);
var_dump($limitit->getInnerIterator());
Expected result:
----------------
object(LimitIterator)#2 (0) {
/* some content */
}
object(ArrayIterator)#1 (1) {
["storage":"ArrayIterator":private]=>
array(1) {
["test"]=>
string(4) "test"
}
}
string(25) "O:13:"LimitIterator":0:{...........}"
object(LimitIterator)#3 (0) {
/* some content */
}
object(ArrayIterator)#1 (1) {
["storage":"ArrayIterator":private]=>
array(1) {
["test"]=>
string(4) "test"
}
}
Actual result:
--------------
object(LimitIterator)#2 (0) {
}
object(ArrayIterator)#1 (1) {
["storage":"ArrayIterator":private]=>
array(1) {
["test"]=>
string(4) "test"
}
}
string(25) "O:13:"LimitIterator":0:{}"
object(LimitIterator)#3 (0) {
}
NULL
