Getting 404 error while accessing php page in apache in simple php application?

I created a simple php file sample.php

under/var/www/project/dummy/test/sample.php

Here httpd.conf

 Listen 8080
    <VirtualHost *:8080>
            ServerName example.com
            DocumentRoot "/var/www/projects/dummy/test"
            <Directory "/var/www/projects/dummy/test">
                AllowOverride All
                Allow from all
            </Directory>
    </VirtualHost>

      

        
        
        
      

    

Here sample.php

(just checking if memcache is enabled)

<? php

if(class_exists('Memcache')){
  echo "found";
}

?>

      

        
        
        
      

    

when i turn to localhost:8080/sample.php

or localhost:8080/test/sample.php

i get 404 error

. I can't figure out what's going wrong.

It worries me why localhost

, if it doesn't work.

To add to that does www.example.com/sample.php

n't even work.

thanks for the help

PS: I mapped the ip address in the /etc/hosts

following:

127.0.0.1 example.com www.example.com localhost

why localhost

doesn't it work?
