/var/www/ is where you'll find your documents.

Create phpinfo.php with

in it and then go to localhost to see whats on your system.

I already seen that folder but I dont yet know how to control permissions in
ubuntu
I tho its my pc I dont seem to have permision for rw for that folder.

/var/www/ is a root folder.
Open it as root then create a folder in there under your username and
then you wont have to worry about that.

sorry if i sound so newbie, cos I'm, how do I open a folder as root
I login with the user name I installed ubuntu with and still have
restrictions to root folders.
\could you pls tell me how to open root folders??

sudo chown username filename
