How to change a html website to php?

My current website index file is in html and I would like to add something called tracewatch to keep track of my web stats. The only problem is that it says in order for it to work "Make sure the file is processed by the server as php (if the file extension is .html or .htm change it to .php)"

How can I make to to where my index file is php and I can use this?

 

its easy just save your page from .html to .php. it will work without any php code inside them.

 

There are two ways:
1. Put the following lines in .htaccess

AddType application/x-httpd-php .php .htm .html
AddHandler x-httpd-php .php .htm .html

Code (markup):

so your html page will be processed as php.

2nd.
Add this line:

DirectoryIndex index.php

Code (markup):

Rename your index.html to index.php and put your php code there.

 

worked perfect! thank you!
