1.下载php Dehug;php server

2.下载php环境

下载地址：https://www.php.net/downloads.php

3.配置环境变量

C:\Users\hacker>php -v
PHP 8.3.3 (cli) (built: Feb 13 2024 23:17:12) (ZTS Visual C++ 2019 x64)
Copyright (c) The PHP Group
Zend Engine v4.3.3, Copyright (c) Zend Technologies有这样的回显，就代表安装成功

5.配置php.ini文件

刚下载后，php目录中是没有php.ini文件的，需要我们自己设置，复制php.ini-development文件，粘贴，将粘贴后的文件改为php.ini

6.设置vscode

右上角文件—> 首选项-----> 设置------>php

    "security.workspace.trust.untrustedFiles": "open","php.validate.executablePath": "D:/tool/php8/php.exe","php.debug.executablePath": "D:/tool/php8/php.exe","phpserver.phpConfigPath": "D:/tool/php8/php.ini","phpserver.phpPath": "D:/tool/php8/php.exe",

添加上面的代码，路径改为自己php的路径

6.测试

OK

解决方法：

修改php.ini文件,将下面前面的·;·给删除extension=mbstring  
extension=exif  
extension=mysqli
