Moving up/down an item in the array by its value

Question

I cannot find an effective solution on rearranging/swapping an array item by its value by shifting by - 1 or + 1. I\'m making an order on tables, i

Answer 1

$ret = array();
for ($i = 0; $i < count($array); $i++) {
    if ($array[$i] == $desired_item_to_move && $i > 0) {
        $tmp = array_pop($ret);
        $ret[] = $array[$i];
        $ret[] = $tmp;
    } else {
        $ret[] = $array[$i];
    }
}

This will move up all instances of the desired element, putting the new array into $ret.
