PHP on UBuntu

Hi guys,
I want to install PHP, MYSQL and Apache on UBuntu machine. I ran
these commands. commands ran and did'nt give any errors but did'nt say
comments either and i dont see any /var/www directory.

Do i have to download something or ubuntu comes with everything?

Any help will be much appreciated.

Thanks.
