php - How do I output certain index values from a foreach array? -

this structure in database:

items    |itemlink ---------------------- kill bill|kill bill link preman   |preman link 

this code:

$db = new pdo("mysql:host=$hostname;dbname=$database", $username, $password);              $items = 'select items menus';             $itemlink = 'select itemlink menus';              $itemquery = $db->query($items);             $linkquery = $db->query($itemlink);              $fetchitem = $itemquery->fetchall(pdo::fetch_assoc);             $fetchlink = $linkquery->fetchall(pdo::fetch_assoc);              $merged = array_merge($fetchitem,$fetchlink);              foreach($merged $entry) {             foreach( $entry $key => $value ) {            }         } 

from above code, how output items' datas?
