Marcus, deal with this. Previous Comments: ------------------------------------------------------------------------ [2008-10-06 10:23:25] exceptione at hotmail dot com Might be the case indeed. I wanted to add a comment over there, but I am not allowed to. So here: > How could you say this is not a bug? Please reconsider! > There is one invariant which says: »the pointer in all new iterators points at the first element of the collection that has to be iterated.« > > Hence a new iterator a that wraps another new iterator b points to the first element of b. I am very happy with and grateful for the SPL contribution to php. I really hope the behaviour from all iterators from the iterator zoo will be consistent. I think these bugs are certainly no bogus. It's a contract violation and that's painful to me. ------------------------------------------------------------------------ [2008-10-05 18:02:10] [EMAIL PROTECTED] That looks like #44063 ------------------------------------------------------------------------ [2008-10-04 14:57:34] exceptione at hotmail dot com Note that one get get the expected behaviour from the implementation in ext\spl\internal\cachingiterator.inc after correcting the following bugs in that file: add private $flags as class member on line 50 change flags into $flags on line 50 delete CIT_ prefix ------------------------------------------------------------------------ [2008-10-04 14:52:05] exceptione at hotmail dot com Description: ------------ In order to use a new CachingIterator of RecursiveCachingIterator, one needs to do a rewind() or next() to get current() pointing to the first element. This is unlike the other Iterators. Reproduce code: --------------- $arr = array(1,2,3,4,5); $it = new CachingIterator(new ArrayIterator($arr)); var_dump($it->current()); echo PHP_EOL; $it->next(); var_dump($it->current()); echo PHP_EOL; Expected result: ---------------- int 1 int 2 Actual result: -------------- null int 1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46227&edit=1
