如何获取数组键值并计算一个数组对象中的值

我怀疑在 php 数组中获取数组键值并计算 php 数组中重复的相同键。这里我通过一个变量发布我的数组对象输出，我正在获取这些数据。这里我的要求是在这个数组中，我有 [room_type] 和 [meal_type]。

这里 [room_type] => APARTMENT ONE BEDROOM 是这个数组中的 3 次。所以我需要的结果是 3 x APARTMENT ONE BEDROOM 这里 [room_type] => APARTMENT TWO BEDROOM 是这个数组中的 2 次。所以我需要的结果是 2 x APARTMENT TWO BEDROOM 这里 [room_type] => APARTMENT THREE BEDROOM 是 1 次出现在这个数组中。所以我要求的结果是 1 x APARTMENT THREE BEDROOM

$room_details =  
Array
(
    [0] => stdClass Object
        (
            [id] => 4508
            [api] => hotelbeds
            [room_no] => 1
            [room_type] => APARTMENT ONE BEDROOM
            [meal_type] => ONE ROOM
            [updated_on] => 2019-01-16 13:03:17
        )

    [1] => stdClass Object
        (
            [id] => 4509
            [room_no] => 2
            [room_type] => APARTMENT TWO BEDROOM
            [meal_type] => TWO ROOMS
            [updated_on] => 2019-01-16 13:03:09
        )

    [2] => stdClass Object
        (
            [id] => 4510
            [room_no] => 3
            [room_type] => APARTMENT ONE BEDROOMS
            [meal_type] => TWO ROOMS
            [updated_on] => 2019-01-16 13:03:38
        )

    [3] => stdClass Object
        (
            [id] => 4511
            [room_no] => 3
            [room_type] => APARTMENT TWO BEDROOMS
            [meal_type] => TWO ROOMS
            [updated_on] => 2019-01-16 13:03:38
        )

    [4] => stdClass Object
        (
            [id] => 4512
            [room_no] => 3
            [room_type] => APARTMENT THREE BEDROOMS
            [meal_type] => THREE ROOMS
            [updated_on] => 2019-01-16 13:03:38
        )

    [5] => stdClass Object
        (
            [id] => 4513
            [room_no] => 3
            [room_type] => APARTMENT ONE BEDROOMS
            [meal_type] => ONE ROOM
            [updated_on] => 2019-01-16 13:03:38
        )
)

这个结果我想像这样显示在一个 div 标签中。

<div class="roomtype">
<p>
3 x APARTMENT ONE BEDROOM
2 x APARTMENT TWO BEDROOM
1 x APARTMENT THREE BEDROOM
</p>
</div>

[meal_type] => ONE ROOM 进入这个数组 2 次所以结果是 2 x ONE ROOM [meal_type] => 两个 ROOMS 进入这个数组 3 次所以结果是 3 x TWO ROOMS [meal_type] => 三个房间进入这个数组 1 次所以结果是 1 x 三个房间 这个结果我想在另一个 Div 标签中显示这样。

<div class="mealtype">
<p>
2 x ONE ROOM 
3 x TWO ROOMS
1 x THREE ROOMS
</p>
</div>

我试过下面的代码不起作用，任何人都可以帮忙解决这个问题。

                                        For Meal Type 
                                        --------------
                                        $countedValues = array_count_values($room_details->meal_type);
                                        //Build strings from value and display them.
                                        foreach( $countedValues as $roomType=>$count ){
                                            echo $count . ' x ' . $Mealtype . '<br />';
                                        }

                                        For Room Type 
                                        --------------
                                        $countedValues = array_count_values($room_details->room_type);
                                        //Build strings from value and display them.
                                        foreach( $countedValues as $roomType=>$count ){
                                            echo $count . ' x ' . $roomType . '<br />';
                                        }
