在foreach元素中添加空间

Question

i have two foreach operations like below.

    $sql = "select region_name from ".$GLOBALS['ecs']->table('region') . " where region_id in(".$order['province'].",". $order['city'].",".$order['district'].")";
    $address = $GLOBALS['db']->getAll($sql);
    foreach($address as $vo){
        $region .= $vo['region_name'];
    }
    $order['1address'] = $region.$order['1address'];
    return $order;
}

Here's a sample of the output data:

AlabamaColorado

How i want it to be

Alabama Colorado

The only thing wrong is I could not separate Alabama and Colorado with blank space. It might be an easy operation but how? Any idea?

Thanks a lot.

try this:

if ($region == '') {
    $region = $vo['region_name'];
} else {
    $region .= ' ' . $vo['region_name'];
}
