on the last request it is not clear what you specifically want.
For the first two - you can not mix the names of variables, you will sometimes get out errors.

Or so you can:

$resclient = mysqli_query($GLOBALS["___mysqli_ston"], "SELECT name FROM clientselect WHERE id = ".$user['clientselect']) or sqlerr(__FILE__,__LINE__);
$row = mysqli_fetch_array($resclient);if($row){$clientselect = "$row[name]";}
