Importing and accessing existing PHP application into XAMPP

I am new to PHP (have been a Java guy all my years :-) but understand the basics of it. For an existing application on which I need to fix some bugs, I need to import it into XAMPP.

I tried putting all the application folders (and files) into the htdocs folder of XAMPP. However, that does not work. The server does list the new project when I navigate to "http://localhost" but when I click on my project (that I copied), the index.php page fails to come up. It simply says page not found.

I would like to know开发者_如何学Python a couple of things as listed below...

1) Is there something wrong I am doing for the project to be hosted on XAMPP?

2) One peculiar thing that I noticed was that when the application browses to http://localhost/MyProject/index.php , it gets redirected to http://www.localhost/index.php . Is there a URLRewriter (or kind) which is doing this? If yes, where I can find the same within my project?

3) How can I identify the framework that the existing code is using? I can see M-V-C named class.php files

Any pointers would be much helpful for me to start debugging and learning PHP.

Thanks!!
