Subject: Re: [PHP-DEV] RFC array functions
From: helly@php.net (Marcus Boerger)

Hello Eric again,

  forget the last mail, you're right it is hasNext() in php, too. So it
should be array_has_next() as well. Thanks to michael for reminding me.
I got confused with the original implementation (i shouldn't have changed
the name).

best regards
marcus
