從WordPress對象數組中獲取數據？

Question

我正在嘗試獲取WordPress用戶的價值。我正在嘗試使用get_users（）wp函數。我如何從這個數組對象中得到roles鍵的[用戶角色]值。 我的PHP代碼

echo '<pre>'; 
var_dump(get_users()); 
echo '</pre>'; 

什麼返回下面的代碼

array(4) { 
     [0]=> 
     object(WP_User)#510 (7) { 
     ["data"]=> 
     object(stdClass)#506 (10) { 
      ["ID"]=> 
      string(2) "12" 
      ["user_login"]=> 
      string(4) "demo" 
      ["user_pass"]=> 
      string(34) "$P$Bp7wAWdn9qAPehmbEVcGz7DGGjc.lm1" 
      ["user_nicename"]=> 
      string(4) "demo"
