从数组中回显键和值

I have an array called $topProductIdResults and it looks like the following:

我有一个名为$ topProductIdResults的数组，它看起来如下所示：

Array ( [11497522] => 2  )

The keys are prodcuct ID's and the value is the number of 5 star ratings that the product has recieved.

钥匙是产品ID，价值是产品收到的5星评级数。

I want it to echo out this data using a loop. However I can't work our how to echo out both the key and value. Sometimes there will be several product ID's and number pairs in this array. Please let me know where I'm going wrong. My code so far is:

我希望它使用循环回显这些数据。但是我无法理解我们如何回应键和值。有时在这个数组中会有几个产品ID和数字对。请让我知道我哪里出错了。到目前为止我的代码是：

foreach ($topProductIdResults as $prod) {
    echo $prod[0];
    echo $prod[1];
}

which just echo's 22 at the moment. I want it to echo 11497522 2

这只是回声的22。我希望它能回应11497522 2
