It's a side-effect of the implementation. It could be fixed if I forced
all arguments to be passed by reference, but that means that you can't
specify SORT_* constants directly as arguments..

When called inside a function array_multisort changes the global
variables instead of the local copy the function should be working
with.
<?php
$sortKeys = array(3, 2, 4, 1, 5);
$a = array(111 => '111', 222 => '222', 333 => '333', 444 => '444',
555 => '555');
echo "initial arrays:<br>";
echo "sortKeys: "; var_dump($sortKeys); echo "<br>";
echo "a: "; var_dump($a); echo "<br>";
echo "<br>";
msortWithRef($sortKeys, $a);
echo "after msortWithRef:<br>";
echo "sortKeys: "; var_dump($sortKeys); echo "<br>";
echo "a: "; var_dump($a); echo "<br>";
echo "<br>";
msortWithoutRef($sortKeys, $a);
echo "after msortWithoutRef:<br>";
echo "sortKeys: "; var_dump($sortKeys); echo "<br>";
echo "a: "; var_dump($a); echo "<br>";
function msortWithoutRef($array1, $array2)
{
array_multisort($array1, $array2);
}
function msortWithRef($array1, $array2)
{
array_multisort(&$array1, &$array2);
}
?>
output:
initial arrays:
sortKeys: array(5) { [0]=> int(3) [1]=> int(2) [2]=> int(4) [3]=>
int(1) [4]=> int(5) }
a: array(5) { [111]=> string(3) "111" [222]=> string(3) "222" [333]=>
string(3) "333" [444]=> string(3) "444" [555]=> string(3) "555" }
after msortWithRef:
sortKeys: array(5) { [0]=> int(3) [1]=> int(2) [2]=> int(4) [3]=>
int(1) [4]=> int(5) }
a: array(5) { [111]=> string(3) "111" [222]=> string(3) "222" [333]=>
string(3) "333" [444]=> string(3) "444" [555]=> string(3) "555" }
after msortWithoutRef:
sortKeys: array(5) { [0]=> int(1) [1]=> int(2) [2]=> int(3) [3]=>
int(4) [4]=> int(5) }
a: array(5) { [0]=> string(3) "444" [1]=> string(3) "222" [2]=>
string(3) "111" [3]=> string(3) "333" [4]=> string(3) "555" }
