显示 json 数据条件

我有一个数据，我只想显示1个数据，从JSON数据不知道，只显示1个数据。 我想将此数据复制到我的页面。

这是我的代码杰森.php

  <?php 
    $response = curl_exec($curl);
            $err = curl_error($curl);
            curl_close($curl);
            if ($err) {
              echo "cURL Error #:" . $err;
            } else {
                $array = json_decode($response, true);
                echo '<pre>'; 
                print_r($array);
            } ?>

这是我的数据是这样的
