Req #39541 [Opn->Wfx]: next_key() and prev_key()

I wonder what actual use cases that would have; it's unlikely to be common, and there are several ways to accomplish that without introducing these new functions (e.g. for-loop over array_keys()). Besides that, this feature request is 15 years old, and got almost no traction, so I'm closing as WONTFIX. If you, or anybody else for that matter, is still interested in this feature, please pursue the RFC process[1].

Presently, one must use prev()/key() next()/key() and these both affect the array pointer which is inconvenient when looping through an array with the intention of comparing the current item to its immediate neighbors. With next_key() and prev_key() one could get the keys and then directly lookup the neighboring items without affecting the current position during looping. ------------------------------------------------------------------------ [2006-11-17 02:37:46] boots@php.net Description: ------------ It would be handy if PHP had functions to get the current and previous keys in an array without affecting the current array pointer.
