mysqli::real_connect(): (HY000/1045): Access denied for user ‘pum’@‘localhost’ (using password: NO)

此錯誤資訊為MySQL密碼錯誤所導致，xmapp中預設的密碼為空，由於我計算機本身安裝著MySQL，在配置xampp環境時，出現賬號密碼錯誤。
解決方案：找到目錄xmapp\phpMyAdmin\config.inc.php修改配置檔案
找到
c f g [ ′ S e r v e r s ′ ] [ cfg['Servers'][ cfg[′Servers′][i][‘user’] = ‘root’;

c f g [ ′ S e r v e r s ′ ] [ cfg['Servers'][ cfg[′Servers′][i][‘password’] = ‘’;
和
c f g [ ′ S e r v e r s ′ ] [ cfg['Servers'][ cfg[′Servers′][i][‘controluser’] = ‘pum’;
c f g [ ′ S e r v e r s ′ ] [ cfg['Servers'][ cfg[′Servers′][i][‘controlpass’] = ‘’;

將其修改為自己的使用者名稱和密碼
c f g [ ′ S e r v e r s ′ ] [ cfg['Servers'][ cfg[′Servers′][i][‘user’] = ‘root’;
c f g [ ′ S e r v e r s ′ ] [ cfg['Servers'][ cfg[′Servers′][i][‘password’] = ‘1234’;

c f g [ ′ S e r v e r s ′ ] [ cfg['Servers'][ cfg[′Servers′][i][‘controluser’] = ‘root’;
c f g [ ′ S e r v e r s ′ ] [ cfg['Servers'][ cfg[′Servers′][i][‘controlpass’] = ‘1234’;

問題成功解決
