Subject: Re: [PHP-DEV] array_seek function

> Hi Patrick

> That's of course possible, but that would only allow seeking to a relativ=
e position to where the array pointer is at that moment. The functionality =
also gets a bit ambiguous by adding an optional parameter. You're not going=
 to the next or prev position of the array anymore.

You could always use reset() in combination with next($int). The main
benefit I see doing so is that you can do something like:

reset($array);
$jump =3D 3;
while ($elem =3D next($jump)) {
    // Some treatment that needs to be done on every $jump element
}

Which would be slower and less readable with array_seek() of course,
depends on your use case!

> And I think functions like next, prev, current etc should be kept easy to=
 use. If you want seek-like functionality, use the designated array functio=
n for that (if this one should make it into php, that is).

Well, it wouldn't be a mandatory option of course for BC. It would
jump forward/backward X elements just where X is 1 by default. It
could make sense to have both maybe?

Let's wait other's opinion.

Cheers,
Patrick
