Construct a new array whose elements are the original array’s keys, values, and also position:
$temp = array();
$i = 0;
foreach ($array as $key => $value) {
$temp[] = array($i, $key, $value);
$i++;
}
Then sort using a user-defined order that takes the original position into account:
uasort($temp, function($a, $b) {
return $a[2] == $b[2] ? ($a[0] - $b[0]) : ($a[2] < $b[2] ? 1 : -1);
});
Finally, convert it back to the original associative array:
$array = array();
foreach ($temp as $val) {
$array[$val[1]] = $val[2];
}
