Subject: Re: [PHP-DEV] [RFC][Under Discussion] Add functions
 array_key_first()and array_key_last()
From: levim@php.net (Levi Morrison)

I don't think I'm getting all the mail I am supposed to. I hope this gets seen.

I propose 2 functions *only* which I believe covers the use-cases that
all 4 of these do and more, with shorter names, and the ability to
discern whether the call succeeded or not.

    list($key, $value) = array_first($input);
    // $key will be null if the call failed

    list($key, $value) = array_last($input);
    // $key will be null if the call failed

I have tested it with user-land functions and seems to work as
intended in all success and failure conditions. Verification that it
works as intended with internal functions is necessary but this seems
a much better proposal to me.
