Как вывести позиции из бд по значению одного поля (php, mysqli)?

$db = new mysqli("localhost", "root", "", "gallery"); 
$items = $db->query ("SELECT * FROM table"); 

while ($row = $items->fetch_assoc())
{
    if ($row['g_id'] != 1) continue;
    echo '
    <img src="'.$row["img_1"].'" alt="">
    <img src="'.$row["img_2"].'" alt="">
    <textarea readonly name="text" placeholder="размеры">'.$row["text"].'</textarea>';
}

$db = new mysqli("localhost", "root", "", "gallery"); 
$items = $db->query ("SELECT * FROM table"); 
$itemsByG = array();
while ($row = $items->fetch_assoc())
{
    if(!isset($itemsByG[$row['g_id']]))
    {
        $itemsByG[$row['g_id']] = array();
    }
    $itemsByG[$row['g_id']][] = $row;
}
