PHP数据处理

Question

嗨，我有这个数据，我想要改变它中的一些东西，我想用PHP来改变它，问题是我不知道如何访问那些特定的数据，它存储在一个变量中，错误地发布了我下面的代码，我也标记了我想要更改的数据。

      "realtimeRoutingApiState" : "DISABLED"
    } ],
    "defaultOfferRedirectMode" : "DOUBLE_HTML"
  }
}

这是我的代码：

$wh = curl_init();

            curl_setopt($wh, CURLOPT_URL, "https://core.voluum.com/campaigns/" . $id);
            curl_setopt($wh, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($wh, CURLOPT_CUSTOMREQUEST, "GET");


            $head = array();
            $head[] = "Cwauth-Token: " . $tok;
            curl_setopt($wh, CURLOPT_HTTPHEADER, $head);

            $resulta = curl_exec($wh);
            if (curl_errno($wh)) {
                echo 'Error:' . curl_error($wh);
            }
            echo "Request:" . "<br>";
            echo '<pre>' . print_r($resulta, true) . '</pre>';
            $resulta->pathGroups->active='true';

我真的不知道我做的是不是对的。有人帮我--请尝试使用json_decode --这里是我使用json_decode的代码：

$wh = curl_init();

            curl_setopt($wh, CURLOPT_URL, "https://core.voluum.com/campaigns/" . $id);
            curl_setopt($wh, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($wh, CURLOPT_CUSTOMREQUEST, "GET");


            $head = array();
            $head[] = "Cwauth-Token: " . $tok;
            curl_setopt($wh, CURLOPT_HTTPHEADER, $head);

            $resulta = curl_exec($wh);
            if (curl_errno($wh)) {
                echo 'Error:' . curl_error($wh);
            }
            echo "Request:" . "<br>";
            $campinfo = json_decode($resulta, true);
            echo '<pre>' . print_r($campinfo, TRUE) . '</pre>';
            foreach($campinfo['pathsGroups'] as $datacamp){
                echo $datacamp['active']=1;

是的，我用这段代码更改了值，但我的问题是如何将值返回到$resulta变量，在提交到服务器之前，我需要将所有数据放在一起。

Answer 1

试试这个..。

$arr = json_decode($json);
$arr->pathsGroups[0]->active = 'true';

Answer 2

请使用json_decode()，如：

$arr = json_decode($json, true);   // 2 parameter is true so that it returns an array instead of object

它将将json数据转换为数组并相应地使用它。
