Linux Xampp中的访问被拒绝

I'm using Ubuntu 14.04. I'm new to Linux platform. I tried to run xampp in my browser. It showed the message "Access Denied". Please tell me how to run a php file in Linux using xampp.

1. check if you have php php5 ... installed if not apt-get
2. check if apache2 is running if you are not sure service apache2 restart
3. also chmod -R 777 the directory of your project

4. edit xampp/apache/conf/extra/httpd-xampp.c­onf and at the last paragraph change

   Deny from all 
   

   to

   allow from all
