Hi

There's a problem in your comparison callback, you have the same condition in first and second 'if'.
And yes, after first foreach you have a $value is a reference to the last element of the array. So when you do the second foreach (without unsetting $value), it rewrites value of array's first element.

Description:
------------
Array $test soured after use link in foreach.

Test script:
---------------
$test = array(1 => 1, 2 => 2, 3 => 3);
foreach($test as $key => &$value)
{
}

uasort($test, function($a, $b) {
  if($a > $b)
    return -1;
  else if($a > $b)
    return 1;
  else
    return 0;
});

print_r($test);
foreach($test as $key => $value)
{
}
print_r($test);

Expected result:
----------------
Array
(
    [3] => 3
    [2] => 2
    [1] => 1
)
Array
(
    [3] => 1
    [2] => 2
    [1] => 1
)
