要指示phpMyAdmin使用mysqli扩展名，您必须在config.inc.php

To instruct phpMyAdmin to use mysqli extension you have to add the following line to your config.inc.php

/* Select mysqli if your server has it */
$cfg['Servers'][$i]['extension'] = 'mysqli';

您不能从phpMyAdmin内部更改此设置.您可能需要让您的虚拟主机为您做到这一点.

You can not change this setting from inside phpMyAdmin. You'll probably have to ask your web host to do that for you.
