The process and precautions for upgrading PHP to 5.3.3 under windows_PHP tutorial

In fact, the process of upgrading from 5.3.0 to 5.3.3 is quite simple, but it is a bit troublesome to modify my own program. I encountered a small problemAfter the upgrade, my project can no longer connect to mysql. The reason is the problem of the database configuration string. Just change localhost to 127.0.0.1 .
