But There is a problem, you can't write in to the folder /var/www as ordinary user, it needs root privilege . (I am using gksu for solving this proble, it will ask for your sudo password)

open a terminal type the following

$cd /var/www

$ gksu gedit helloworld.php

write the program

<?php
 echo "hello world";
?>
