未捕获的错误：调用未定义函数mysql_connect（）-WordPress设置

我正在尝试在Windows 10的Nginx上安装wordpress，将无法完成安装程序，在输入数据库连接信息后会看到以下信息：

您的网站上存在严重错误。

PHP日志文件中的错误

堆栈跟踪：＃0 C：\ nginx \ html \ wp \ wp-admin \ setup-config.php（310）：wpdb-> db_connect（）＃1 {main}抛出C：\ nginx \ html \ wp \ wp -includes \ wp-db.php 1670 [2020年8月30日12:55:09 UTC] PHP致命错误：未捕获错误：调用C：\ nginx \ html \ wp \ wp-中未定义的函数mysqli_connect（） includes \ wp-db.php：1670

用wp-db.php中的mysqli_connect（）替换mysql_connect（）不能为我解决问题

在启动Nginx之前php-cgi始终在127.0.0.1:9000上运行
