我只想把字符串作为字符串。当我试图通过$auth[“token”]获取字符串时，它一直显示字符串类型，我无法单独获取字符串
`

$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => 'https://api.nowpayments.io/v1/auth',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => '',
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 0,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => 'POST',
    CURLOPT_POSTFIELDS => '{
        "email": "email",
        "password": "pass" 
    }',
    CURLOPT_HTTPHEADER => array(
        
         
      'Content-Type: application/json'
    ),
  ));

$response = curl_exec($curl);
var_dump($response);
$auth =json_decode($response,true);
var_dump($auth);
curl_close($curl);
$authtoken=$auth["token"];
echo $authtoken;

`
页面显示此“错误”

正如您所看到的，我只希望$authtoken每次都不带“string（128）”字符串信息
这里使用var_export（$auth）;

'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6IjYzODUzMjU3MzkiLCJpYXQiOjE2NjgzMTE5ODYsImV4cCI6MTY2ODMxMjI4Nn0.nK0WDgA9fwhVT6EqNimQm32NlRh5UL4kv6x3AAP_yi8',

这里使用var_export（$response）;
