Either by a loop:
$filtered = array()
foreach ($res as $key => $item){
if($res['age']!=0) $filtered[] = $item;
//or preserve keys by $filtered[$key] = $item;
}

Or indeed by array_filter:
$filtered = array_filter($res,create_funtion('$v,$k','return
$v['age']!=0;'));

Where are you getting the data from by the way? It might be easier to
tackle this at the source.
