Deploying web-application on apache2 server

Question

I have installed/setup PHP5 and Apache2 server on Ubuntu and trying to deploy a dummy project on it.

The server is up and running.but the URL http://localhost/DemoWebApp gives me

Apache/2.4.7 (Ubuntu) Server at localhost Port 80.

What am I doing wrong or how do I set it up correctly?

Edit:

Project structure:

Solution 1

move DemoWebApp into html folder and it should work

Solution 2

Set DocumentRoot in /etc/httpd/httpd.conf to /var/www or move DemoApp folder to /var/www/html
