remember more? Nikita and Bob, maybe?
Yeah, I'm one of those people. In PHP 7 the most important user of the IAP,
foreach, was switched to use a more robust mechanism. I believe that at
this point, the concept of an internal array pointer has outlived its
usefulness and we should be working toward removing any APIs that publicly
expose it, including each and the next/current/key family of functions. I
will propose to deprecate each() in particular for PHP 7.2, because it is
both more problematic and more useless than the others, but I'd like to see
the others go away in the long term as well. If people want fine-grained
control over array iteration, they should use an external iterator (aka
ArrayIterator), not an internal one.
I'm sure I've suggested this before, but couldn't we drop the IAP
without getting rid of these functions? They could maintain their own
map of arrays to positions (effectively emulating the IAP), for example.
Thanks.
