Question

我正在尝试打印字段名称：实体名称并收到错误说＆＃34;尝试获取非对象的属性＆＃34;

$accrdNo = '3001044';

$url = "http://localhost:8080/webservice/index.php?id=$accrdNo";

$client = curl_init($url);

curl_setopt($client, CURLOPT_URL, $url);
curl_setopt($client, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($client, CURLOPT_RETURNTRANSFER, 1);

$result = curl_exec($client);

$encoded = json_encode($result, true);
