Hi all,
I just want to add some information that I feel it's missing in that
discussion - I'm sorry if it was mentioned already.
1. It's already possible to extract the key and value of any index
position of an array using array_slice: https://3v4l.org/mib99
2. "array_[key|value]_[first|last]($array)" is in my opinion not a good
option as it lacks the possibility to extract key/value from any position.
Something like "array_[key|value]_index($array, $index)" where $index
would be the index position or negative index position from right.
Thanks,
Marc

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.
Can I vote "heck no" to any function that does multi-return, thus making it
impossible to chain or pass directly to another function? That's an idiom
that just doesn't make sense in PHP.
