Yes, that's an intentional change; if you need a reference, there is array_walk for that.

Description:
------------
array_map no longer passes by-reference.

This has broken a lot of things for us.

This very well may be an intentional change, but I didn't see it noted, and if it is, it should be documented on the array_map page as a change?

Test script:
---------------
<?php

// https://3v4l.org/BdWq7

$data = array(
    array(1,2,3),
    array(4,5,6),
);

$data = array_map('reset', $data);

print_r($data);

Expected result:
----------------
Array
(
    [0] => 1
    [1] => 4
)


Actual result:
--------------
Warning: reset(): Argument #1 ($array) must be passed by reference, value given in /in/BdWq7 on line 8
