我目前正在嘗試在變量中獲取JSON解碼輸出的每個標題這就是對我有用的卷曲$curl = curl_init();curl_setopt_array($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 $name;當我刪除干擾背后的[0]時，我得到一個空白$name。有誰知道我該如何解決這個問題？謝謝
