YII php framework localhost works but 127.0.0.1 does not

Question

I'm following a book "Agile Web Application Development with Yii" and I am setting up a database connection to the Yii application through an application component.

I followed the books instructions and said the mysql db host is 127.0.0.1. I ran a test and it failed to connect.

Then I changed the host to "localhost" and it works.

Does anyone know why this is the case?

Answer 1

Check the file name host at this location

C:\WINDOWS\system32\drivers\etc

Check the default value of localhost in the host file, by default it should be 127.0.0.1 if not, change it to 127.0.0.1. Now try to access your wamp server by using 127.0.0.1 on any web browser.
