Warning:
in the last version of PHP uksort() may refuse to sort the array and return false if there is a
global instruction inside the comparison function!
See http://phpquirks.blogspot.com/2010/09/globals-or-global.html
e.g.
<?php
function my_sort($a, $b)
{
global $arr;
return $arr[$a]['value'] - $arr[$b]['value'];
}
?>
