Recently I had a client that was running a Magento eCommerce store and wanted to use WordPress as their blog CMS. That is all fine and dandy as we just installed WordPress in a subdirectory and had it up and running in no time. The next tasks was to make the WordPress blog look like it is integrated into the Magento store by pulling the Magento header and footer into the WordPress theme.
To do this, I ended up using cURL to fetch the HTML of the Magento header between two comment tags.. For example, here is the header.php of the WordPress theme.
<?php
/**
* The Header for our theme.
*
* Displays all of the <head> section and everything up till <div id="main">
*
* @package WordPress
* @subpackage Twenty_Twelve
* @since Twenty Twelve 1.0
*/
?><!DOCTYPE html>

<html class="ie ie7" <?php language_attributes(); ?>>
<![endif]-->
<!--[if IE 8]>

curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_close($ch);
?>

You can see around line 36 that I set the URL to fetch to a blank Magento page that was created in Magento. Then around line 48 a regular expression was setup to look for and grab everything between two comment tags.
To setup these comment tags, you will want to edit the .phtml file that the page you are fetching in line 36 is using. To do this, navigate to app/design/frontend/default/themename/template/page/1column.phtml(or whatever page template your page is using in line 36)

You can see around line 43, I inserted the two comment tags that cURL is looking for. Now when your WordPress header loads, it will pull the Magento header. Duplicate the above steps to do the same if you need to pull in the Magento footer as well.
Hope this helps anyone out there looking for a quick and easy solution.
