Question

我正在使用竞争api来检索网站的唯一访问者。这是代码......

$activityurl = file_get_contents("http://apps.compete.com/sites/facebook.com/trended/uv/?apikey=myapikey");

$jsondecoded = json_decode($activityurl);

foreach($jsondecoded as $values)
{

    print_r($values)."<br />";
}

这是我得到的输出..

OKstdClass Object ( [trends] => stdClass Object ( [uv] => Array ( [0] => stdClass Object ( [date] => 201210 [value] => 160962051 ) [1] => stdClass Object ( [date] => 201211 [value] => 163640791 ) [2] => stdClass Object ( [date] => 201212 [value] => 165602717 ) [3] => stdClass Object ( [date] => 201301 [value] => 166238881 ) [4] => stdClass Object ( [date] => 201302 [value] => 165056717 ) [5] => stdClass Object ( [date] => 201303 [value] => 164808579 ) [6] => stdClass Object ( [date] => 201304 [value] => 164131054 ) [7] => stdClass Object ( [date] => 201305 [value] => 163323608 ) [8] => stdClass Object ( [date] => 201306 [value] => 163078120 ) [9] => stdClass Object ( [date] => 201307 [value] => 163864002 ) [10] => stdClass Object ( [date] => 201308 [value] => 163413311 ) [11] => stdClass Object ( [date] => 201309 [value] => 164616160 ) [12] => stdClass Object ( [date] => 201310 [value] => 167403281 ) ) )

我想从上面的

中检索'value'

Answer 1

你可以这样做：

$jsondecoded = json_decode($activityurl, true);

第二个参数意味着：

当为TRUE时，返回的对象将被转换为关联数组。

我希望你知道如何使用数组：）

Answer 2

您需要在循环中提取它们

$activityurl = file_get_contents("http://apps.compete.com/sites/facebook.com/trended/uv/?apikey=myapikey");

$jsondecoded = json_decode($activityurl);
$values = array();

if ($jsondecoded->status === 'ACCESS_DENIED') throw new Exception($jsondecoded->status_message);

foreach($jsondecoded->data->trends->uv as $object)
{
    $values[] = $object->value;
}

var_dump($values)给出了

array(13) {
  [0] =>
  int(160962051)
  [1] =>
  int(163640791)
  [2] =>
  int(165602717)
  [3] =>
  int(166238881)
  [4] =>
  int(165056717)
  [5] =>
  int(164808579)
  [6] =>
  int(164131054)
  [7] =>
  int(163323608)
  [8] =>
  int(163078120)
  [9] =>
  int(163864002)
  [10] =>
  int(163413311)
  [11] =>
  int(164616160)
  [12] =>
  int(167403281)
}

Answer 3

$jsondecoded = json_decode($activityurl,true);  //u will get array type

然后你可以做到

 $trends=$jsondecoded['trends'];

 $uv=$trends['uv'];

foreach $uv as $target
{
 echo $target['data'].' '. $target['value'].'<br/>';
}

从数组返回数据
