$qtwo = str_split_unicode($q); 
$arrlength = count($qtwo);

and then I got:

$where = array();
foreach ( $qtwo as $word ) {
$where[] = "CHS LIKE '%" . $word . "%'";
$where = implode(' OR ', $where);    

if ($q[0] == "#")  {
} else {$results4 = $db->query("SELECT * FROM FOUR WHERE $where");
while ($row4 = $results4->fetchArray()) {

and then a bunch of echoing etc - but the results come back in alphabetical order - first come first served, e.g.:

For anyone who finds Chinese kind of foreign it'd be like searching: GSMLN and getting the results in alphabetical order: GMLNS.

My goal is to get the (output) order the same as the input (order).

Is there a simple order by I can use? or does it get more complicated?

In SQL, tables always are unordered; there is no guarantee that a query uses any specific order.

If you want to get the rows in a specific order, you have to explicitly sort them by using ORDER BY in the query.

If there isn't some table data that you can use directly for sorting, you have to use a CASE expression to map the table values to some values usable for sorting:

         WHEN '隔' THEN 1
         WHEN '山' THEN 2
         WHEN '买' THEN 3
         WHEN '老' THEN 4
         WHEN '牛' THEN 5
