php files connected with mysql server not working

Question

I started a php project in netbeans and connected it with a database in localhost/phpmyadmin. But on running it gives this error on browser..

Why does this happen? How to avoid it?

Here are the codes in the project.. dbconnect.php and index.php. Files are saved in /var/www/html/Testing/ (Testing is name of project).

Edit : I tried URL localhost/Testing/index.php but still gets the same error.

Edit2 : Folder structure of /var/www

Answer 1

Use path like localhost/Testing/index.php. Remove html folder from URL.

Reason ? Linux by default considers PHP files in html folder. So no need to give that folder name in url.

Answer 2

type

localhost

in your browser, it must show you a page with all of the folders in your www directory. then find your desirable folder and click on it, continue this until you get to your index.php file

Answer 3

First try to access the localhost. If all is well configured you will see there all projects. Then access project that you need to see what gives you url

Answer 4

Remove or rename .htaccess the file from the project

you will able to open this project
