How to Set up index.php in Root Folder (WordPress)

I have installed my blog on a sub directory
in root directory called blog.

The address to blog is like below,
http://www.my-domain-name.com/blog/

Now I want my root address refers to the
blog. That means when someone types,
http://www.my-domain-name.com/
It should show my blog.

Here I don't mean a redirection. I want
to create an index.php in root folder
and replace index.html with it.

My blog's index.php contains following
content.

<?php get_header(); ?>
<div class="content">
<div class="primary">
<?php include (TEMPLATEPATH . '/theloop.php'); ?>
</div>
<?php get_sidebar(); ?>
</div>
<?php get_footer(); ?>

PHP:

I can't figure out how to call functions like
get_header() in my custom made index.php
which is in root folder.

Can anyone help me to get this done?

Why don't you simply install the blog in your root folder instead of trying to do it with the index.php. Wordpress is likely to give some errors if the only file in the root folder is the index.

 

Use .htaccess to redirect .Do a search on google if you don't know how to do.

 

I got it done. Here is the How-to guide to do it right.
