提问by Artem
I am setting up PHP and MySQL (Maria DB) on Windows 8.1. I edited php.ini file and uncommented the following lines:
我正在 Windows 8.1 上设置 PHP 和 MySQL (Maria DB)。我编辑了 php.ini 文件并取消了以下几行的注释：

Finaly I managed to settle this stuff. I corrected extension_dir entry (absolute file path was needed) in php.ini file and database connection began to work.
最后我设法解决了这个问题。我更正了 php.ini 文件中的 extension_dir 条目（需要绝对文件路径），数据库连接开始工作。

Check the extension_dir of your current apache directory, i installed 2 php versions and apache, and the problem was in wamp\bin\apache\Apache2.4.23\bin\php.ini , the path of ext was incorrect
查看你当前apache目录的extension_dir，我安装了2个php版本和apache，问题出在wamp\bin\apache\Apache2.4.23\bin\php.ini，ext路径不对
