ID: 39541 User updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: Feature/Change Request Operating System: all PHP Version: 5.2.0 New Comment:
As a minor request, it would be handy if PHP had analogues for the prev() and next() functions but which instead returned keys without affecting the current array pointer. 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.
