The process and precautions for upgrading PHP to 5.3.3 under windows

I upgraded the local development environment without involving the production environment. In fact, the process of upgrading from 5.3.0 to 5.3.3 is quite simple. It is just a bit troublesome to modify my own program. I encountered a small problem and upgraded Later, my project could not connect to mysql. The reason was the problem of database configuration string. I just changed localhost to 127.0.0.1. I will not use localhost again in the future...
