What im trying to allow for is sorting by iterator as well as standard arrays, for example : // assume en_US as default locale $coll = new Collator("en_US"); $iter = new TextIterator("The rain in Spain drop gently on the Plains", TextIterator::WORD); var_dump( $coll->sort($iter)); // returns the sorted list of words $expr = new Regex($patttern, $input, $flags); var_dump($coll->sort($expr, SORT_DESC)); // Sorts matches in descending order > Anyway looking at the code you seem to be using a c-level iterator > manually instead of using it inside foreach() construct. see above... > The first thing i can see is that you use the iterator index while the > source code (zend_interface.h) says: > ulong index; /* private to fe_reset/fe_fetch opcodes */ > Unil now noone tried to emulate this stuff so i am not sure whether this > is correct or not. i wrote this more than ayear ago and i remember copying it from engine code. > The second thing is that you did not use the dtor() handler so you have > a memory leak. which dtor handler ? > To try to answer what i think you want to know: What ever object you use. > If it implements Traversable or derived its zend_class_entry has a > get_iterator function that gets you access to an iteator struct and the > handler table.
