PHP关联数组：存储键和值

Question

我对关联数组很新。只是尝试创建一个动态关联数组。

当前数组 -

stdClass Object
(
    [354] => Array
        (
        )

    [355] => Array
        (
        )

)

尝试获得所需的输出

stdClass Object
(
    [354] => Array
        (
            [activity_desc] = "description"
        )

    [355] => Array
        (
           [activity_desc] = "description"
        )

)

写了一个sql来检查密钥（354,355）并返回说明。

如何将密钥和值存储在344＆amp; 355？

当前代码：

foreach ($report as $key=>$value) 
{
    $where = 'item_id = ' . $key . '';		
	$query = $db->prepare('SELECT activity_desc FROM program WHERE '. $where);
	$query->execute();
	$test = $query->fetch(PDO::FETCH_OBJ);
}

这是我对354的sql返回查询.355将大致相同。

stdClass Object ( [activity_desc] => <p>Send Activity</p>
