Description:
------------
---
From manual page: http://www.php.net/function.array-map
---

Not a dupe of, but related to #43612.

The page says (too far down) that "If the array argument contains string keys then the returned array will contain string keys if and only if exactly one array is passed. If more than one argument is passed then the returned array always has integer keys."

Whereas the actual behaviour is "The returned array will preserve the keys of the array argument if and only if exactly one array is passed. If more than one array is passed, the returned array will have sequential, integer keys."

It would be great if this was official so we could rely on it.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
