Description:
------------
Function array_map always emits warning "Warning: array_map(): Expected parameter 3 to be an array, array given" if third parameter is not an array.

It looks like X in "X given" is type of the second parameter instead of the offending parameter.

Test cases:
array_map('trim', array(), 1); – "array given"
array_map('trim', array(), true); – "array given"
array_map('trim', array(), null); – "array given"

array_map('trim', 1, true); – "int given"
array_map('trim', true, true); – "bool given"


Test script:
---------------
<?php
array_map('trim', array(), true);
?>

Expected result:
----------------
Warning: array_map(): Expected parameter 3 to be an array, bool given

Actual result:
--------------
Warning: array_map(): Expected parameter 3 to be an array, array given
