@requinix: The issue here is that is does the by-reference modification, while it should not. A similar, but slightly different, bug exists in HHVM as well: https://3v4l.org/dp6Lt

I don't see anything to suggest that was supported in the first place. There aren't even user comments doing that.
Besides, if you want to alter the array values then array_map() is more appropriate.

Description:
------------
It would appear that passing by reference in the callable of array_filter no longer functions as expected. I can find no documentation of this change on the array_filter page.
The expected result is seen in 5.3 -> 5.6
Test script:
---------------
<?php
$files = array('AAA', 'BBB', 'CcC');
$files = array_filter($files, function ( &$path ) {
$path = strtolower($path);
return true;
});
print_r($files);
Expected result:
----------------
Array
(
[0] => aaa
[1] => bbb
[2] => ccc
)
Actual result:
--------------
Array
(
[0] => AAA
[1] => BBB
[2] => CcC
)
