我目前正在尝试在变量中获取JSON解码输出的每个标题这就是对我有用的卷曲$curl = curl_init();curl_setopt_array($curl, array( CURLOPT_URL => 'http://api.irail.be/disturbances/?format=json&lang=nl', CURLOPT_RETURNTRANSFER => true, CURLOPT_ENCODING => '', CURLOPT_MAXREDIRS => 10, CURLOPT_TIMEOUT => 30, CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1, CURLOPT_CUSTOMREQUEST => 'POST', CURLOPT_HTTPHEADER => array( 'cache-control: no-cache', 'content-type: application/x-www-form-urlencoded' ),));$response = curl_exec($curl);$err = curl_error($curl);curl_close($curl);// Decode JSON response and get only the data needed:$response = json_decode($response);$response = $response->disturbance[0];var_dump($response);$name = $response->title;echo $name;当我删除干扰背后的[0]时,我得到一个空白$name。有谁知道我该如何解决这个问题?谢谢

您可以通过键访问对象,但“干扰”不是键,而是键可以取的值。type
首先需要筛选数据以仅获取 包含 的项目,然后才能获取标题。type = 'disturbance'
下面是一个示例:
$response = json_decode($response);
$disturbanceItems = array_filter($response, function ($item){return $item->type == 'disturbance';});
echo $disturbanceItems[0]->title ;
