php - 搜索这个json数组的有效方法？

Question

我的程序员无法location从此 json 数组中获取数据（纬度和经度）。foreach一个能找到纬度/经度location:并回显它们的循环是什么？谢谢

$jsonArray = json_decode($jsondata, true);

$jsondata =  {
       "results" : [
          {
             "address_components" : [
                {
                   "long_name" : "2340",
                   "short_name" : "2340",
                   "types" : [ "postal_code" ]
                },
                {
                   "long_name" : "New South Wales",
                   "short_name" : "NSW",
                   "types" : [ "administrative_area_level_1", "political" ]
                },
                {
                   "long_name" : "Australia",
                   "short_name" : "AU",
                   "types" : [ "country", "political" ]

为什么需要循环？您可以通过以下方式直接访问它：

echo $jsonArray['results'][0]['geometry']['location']['lat'];

有多个结果，这将是

foreach( $jsonArray['results'] as $row) { 
    $lat = $row['geometry']['location']['lat'];
    $long = $row['geometry']['location']['lng'];
    echo $lat . ' ' . $long . "\n";
}
