我有这段代码：
return json_decode($body);
此返回来自一个从谷歌获得一些搜索结果的功能。如果我打印它，例如：

现在，我尝试使用函数get_object_vars()，但会输出相同的输出。我想在数组中加入值，但只有[ur] => ; [title] =>和[content]=> ;我该如何实现？
答案 0 :(得分：0)
混合json_decode（字符串$ json [，bool $ assoc = false [，int $ depth = 512 [，int $ options = 0]]]）
只需将第二个参数设置为true;）
答案 1 :(得分：0)
答案 2 :(得分：0)
假设上面的数据保存在名为$returnedData的变量中：
如果您使用return json_decode($body);：
$results = array();
foreach ($returnedData->responseData->results as $result) {
$results[] = array(
'url' => $result->url,
'title' => $result->title,
'content'=>$result->content
);
}
print_r($results);
...如果您使用return json_decode($body,true);：
$results = array();
foreach ($returnedData['responseData']['results'] as $result) {
$results[] = array(
'url' => $result['url'],
'title' => $result['title'],
'content'=>$result['content']
);
}
print_r($results);
