我正在设置一个网络服务器，使用 Debian 10、Apache2、PHP7.3、MariaDB 和 PHPMyAdmin。
当我启动 Apache2 时它会说：
PHP Warning: PHP Startup: Unable to load dynamic library 'mysqli' (tried: /usr/lib/php/20180731/mysqli (/usr/lib/php/20180731/mysqli: cannot open shared object file: No such file or directory), /usr/lib/php/20180731/mysqli.so (/usr/lib/php/20180731/mysqli.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Apache2 可以正常启动，但我想使用它，因此我需要修复它。尝试在 php.ini 中启用它，当我禁用它时，错误仍然存在。每次调整后我都会重新启动 Apache2。
编辑：重新安装 MySQL，MySQLi 工作正常。新错误：
PHP Warning: PHP Startup: Unable to load dynamic library 'mysqli' (tried: /usr/lib/php/20180731/mysqli (/usr/lib/php/20180731/mysqli: cannot open shared object file: No such file or directory), /usr/lib/php/20180731/mysqli.so (/usr/lib/php/20180731/mysqli.so: undefined symbol: mysqlnd_global_stats)) in Unknown on line 0

mysqli.so 位于正确的位置，但文件中出错了。该文件是编译后的代码，因此更改内容实际上不是一个选择。有人能很好地修复这个问题吗？还是需要重新安装？
