You should open your php.ini file located in php folder, and uncomment this line of code:
您应该打开位于 php 文件夹中的 php.ini 文件，并取消注释这行代码：
;extension=php_mysql.dll
So it looks like this:
所以它看起来像这样：
extension=php_mysql.dll
Your php folder location depends on your lampp/wampp installation, if using xampp its located in: xampp/php/php.ini
您的 php 文件夹位置取决于您的 lampp/wampp 安装，如果使用 xampp，它位于：xampp/php/php.ini

The build of your PHP spectifically says '--without-mysql'
您的 PHP 的构建特别指出“--without-mysql”
Therefore, mysql functions will not be available.
因此，mysql 函数将不可用。
You should rebuild.
你应该重建。

Your PHP is configured with --without-mysql.
您的 PHP 配置为--without-mysql.
The documentationdescribes how to configure with mysql extension enabled. You may have your reasons, but PDO would be a better choice here is the documentationfor configuring with PDO mysql.
该文档描述了如何在启用 mysql 扩展的情况下进行配置。您可能有自己的原因，但 PDO 是更好的选择，这里是使用 PDO mysql 进行配置的文档。
