Hello everyone,

I'd like to introduce a new RFC for your consideration and discussion:
https://wiki.php.net/rfc/array_change_keys  This would add a new function
named array_change_keys() which simplifies the process of re-keying an
array.

PHP currently has an array_change_key_case() method, but this only allows
keys to be changed to upper- or lower-case; no method exists to change the
keys to some custom user-defined value.  Although it's absolutely possible
to accomplish this without a special function, the alternate approaches
have several drawbacks:

 - Slower execution time compared to the proposed implementation.
 - Multiple lines and/or function calls are required.
 - Harder to understand the code's purpose with a quick glance.
 - The result of a "foreach" approach cannot be passed into another
function without using an intermediate variable.

A working implementation has been included with the RFC (huge thanks to
Jeremy Mikola for the heavy lifting here!)  I've also requested this patch
be added to 3v4l.org; I'll notify everyone if/when that happens.

I'd greatly appreciate if you could review this RFC and let me know your
thoughts.  I'd be happy to answer any questions you might have.

Regards,

Colin O'Dell
