Question

我无法定位数组中的特定值。我试图瞄准＆＃39; lng＆＃39;和＆＃39; lat＆＃39;我觉得我很接近，并尝试了几种不同的目标方式。目前正在尝试这个：

$json = file_get_contents($jsonurl);
$output = json_decode($json, true);

$latitude=$output['results']['locations']['latLng'][0];
$longitude=$output['results']['locations']['latLng'][1];

JSON是：

array(3) {
  ["results"]=>
  array(1) {
    [0]=>
    array(2) {
      ["locations"]=>
      array(1) {
        [0]=>
        array(19) {
          ["latLng"]=>
