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

此错误信息为MySQL密码错误所导致，xmapp中默认的密码为空，由于我计算机本身安装着MySQL，在配置xampp环境时，出现账号密码错误。
解决方案：找到目录xmapp\phpMyAdmin\config.inc.php修改配置文件
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’] = ‘’;

将其修改为自己的用户名和密码
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’;
