Question

我有一个对象，我想从中显示一个值。

我的对象如下：

Array
(
    [0] => Array
        (
            [0] => Orionstraat 11, 3235 TE Rockanje, Netherlands
        )

    [1] => Array
        (
            [0] => Woonkreek 56, 3206 GT Spijkenisse, Netherlands
        )

    [2] => Array
        (
            [0] => stdClass Object
                (
                    [elements] => Array
                        (
                            [0] => stdClass Object
                                (
                                    [distance] => stdClass Object
                                        (
                                            [text] => 25.2 km
                                            [value] => 25195
                                        )

                                    [duration] => stdClass Object
                                        (
                                            [text] => 30 mins
                                            [value] => 1796
                                        )

                                    [status] => OK
                                )

                        )

                )

        )

    [3] => OK
)

我想在value内返回distance。

所以我这样做了：

foreach($distancedecoded as $route){
  $distance = $route->elements->distance->value;
}
echo $distance;

但这没有显示，为什么会这样？

我也试过了：

$distance = $route[2]->elements->distance->value;

当我得到一个数组而不是一个对象时：

$distancedecoded = json_decode($getdistance, true);

foreach($distancedecoded as $route){
  $distance = $route[2][0]['elements'][0]['distance']['value'];
  $routearray[] = $route;
}

我收到了这些警告：

Warning: Illegal string offset 'elements' in /home/site/public_html/_extern/site/includes/getzip.php on line 105

Warning: Illegal string offset 'distance' in /home/site/public_html/_extern/site/includes/getzip.php on line 105

Warning: Illegal string offset 'value' in /home/site/public_html/_extern/site/includes/getzip.php on line 105

$distancedecoded

的var_dump

object(stdClass)#35 (4) {
  ["destination_addresses"]=>
  array(1) {
    [0]=>
    string(45) "Orionstraat 11, 3235 TE Rockanje, Netherlands"
  }
  ["origin_addresses"]=>
  array(1) {
    [0]=>
    string(46) "Woonkreek 56, 3206 GT Spijkenisse, Netherlands"
  }
  ["rows"]=>
  array(1) {
    [0]=>
    object(stdClass)#36 (1) {
      ["elements"]=>
      array(1) {
        [0]=>
        object(stdClass)#37 (3) {
          ["distance"]=>
          object(stdClass)#38 (2) {
            ["text"]=>
            string(7) "25.2 km"
            ["value"]=>
            int(25195)
          }
          ["duration"]=>
          object(stdClass)#39 (2) {
            ["text"]=>
            string(7) "30 mins"
            ["value"]=>
            int(1796)
          }
          ["status"]=>
          string(2) "OK"
        }
      }
    }
  }
  ["status"]=>
  string(2) "OK"
}

$destination = $distancedecoded->destination_addresses[0];
$origin = $distancedecoded->origin_addresses[0];

$distance = $distancedecoded->rows[0]->elements[0]->distance->value;
$duration = $distancedecoded->rows[0]->elements[0]->duration->value;

如何在此std对象中显示值
