Iterator::rewind: link to reset() function vs rewind() function

The change replaces rewind with reset, but these are different things: reset() is a built-in function that rewinds plain arrays, while Iterator::rewind() is the method foreach actually calls on objects implementing Iterator.

You can follow the call chain in the engine: foreach triggers zend_fe_reset_iterator(), which calls iter->funcs->rewind(iter), wired to zend_user_it_rewind() — which dispatches to the PHP-level rewind method (resolved by name here, called here).

So the original wording was correct. Happy to be wrong if I'm missing something!

Well then maybe As &foreach; always calls <methodname>rewind</methodname> before starting should be replaced with As &foreach; always calls rewind before starting because, as is, at https://www.php.net/manual/en/iterator.rewind.php, in the Note box, where it says, "As foreach always calls rewind() before starting iteration, manually advancing the iterator position" it links to the function that "rewind[s] the position of a file pointer".

For that matter, maybe it could even say As &foreach; always calls this method before starting.

But, as is, it's hyperlinking to a function that affects file pointers.

Suggested change

	As &foreach; always calls <methodname>reset</methodname> before starting
	As &foreach; always calls <methodname>Iterator::rewind</methodname> before starting

You're proposing the page link to itself? Is there precedent for that on php.net? In general I think that that's kinda silly. Like making every instance of "World War "2 on the "World War 2" wikipedia article link to itself... I'm not sure that's a very useful change.

I feel like As &foreach; always calls this method before starting would be better.

@terrafrost I agree with your suggestion. Using this method makes more sense.
