具体步骤:
(推荐教程:php图文教程)
首先打开php.ini配置文件,搜索php_mysqli.dll;
然后设置extension_dir指令
; Windows Extensions ; Note that ODBC support is built in, so no dll is needed for it. ; Note that many DLL files are located in the extensions/ (PHP 4) ext/ (PHP 5+) ; extension folders as well as the separate PECL DLL download (PHP 5+). ; Be sure to appropriately set the extension_dir directive. ;一定要适当地设置extension_dir指令。

最后在php.ini里面搜索extension_dir;
extension_dir = “G:/web/php7.1/ext”
检查G:/web/php7.1/ext安装路径是否存在php_mysqli.dll(如果不存在应该是PHP安装包损坏,请重新下载)。
完成以上步骤就开启成功了。
