请注意，似乎 results包含一个数组 (此处只有一个项)结果;而geometry是一个结果中的一项.

Note that it seems that results contains an array (with only one item in it, here) of results ; and geometry is one item inside one result.

在这里，您可以看到结果的内容由[]分隔-表示它是一个数组.

Here, you can see that results' content is delimited by [] -- which indicates it's an array.

因此，您必须首先访问第一个结果:$geoloc['results'][0]
其中将具有以下几何形状:$geoloc['results'][0]['geometry']

So, you have to first access the first result : $geoloc['results'][0]
Inside of which you'll have the geometry : $geoloc['results'][0]['geometry']

这将允许您获取纬度和经度:

Which will allow you to get the latitude and longitude :

var_dump($geoloc['results'][0]['geometry']['location']['lat']);
var_dump($geoloc['results'][0]['geometry']['location']['lng']);

我想根据您搜索的地址，有时results数组中会有多个项目.

I suppose that, depending on the address you've searched on, you will sometimes have more than one item in the results array.
