I executed it as described in Plan 2, but the result was still the same. I was so mad that I reinstalled PHP, but the error was still the same.

Reset operation: Follow the installation instructions, reinstall, and set up. When I saw doc_root = "c:\inetpub\wwwroot", I woke up from a dream. I changed the home directory of IIS, but there was no change. The configuration of doc_root in PHP.ini resulted in such an error.

There is a lack of analysis of the problem and under what circumstances the problem is caused. For example, this time it was because the home directory was changed. But when encountering a problem, people are often confused and think it may be a server problem or a system problem. The problem is that there is a problem with PHP, and you don't realize what you have changed, but introduced it. The authorities are obsessed with it. Calm analysis is the sword to solve the problem.

Whenever you encounter a particularly strange problem and cannot find the answer online, it is often a very simple problem, such as incorrect parameter settings, etc. It is often because your own ideas and understanding are a bit narrow, or I was too impetuous and didn't read the help documentation.
