SOLVED, I fixed it by changing the %PATH%environment variable to fix it . I added path of all php versions I have to %PATH%, as per my requirement I can arrange it from top to bottom, as CLI will take the first one it will get from Top to bottom in environment variable setting.
已解决，我通过更改%PATH%环境变量来修复它。我添加了所有 php 版本的路径%PATH%，根据我的要求，我可以从上到下排列它，因为 CLI 将在环境变量设置中采用第一个从上到下的路径。
