I want to put the footer in the main div of the page.
How can i dothis in magento?
I'm not sure why you would want to do this, maybe reorganising your page structure would be a better option - a footer is a footer and not really part of the main content.
Nonetheless, this can be easily achieved using layout xml.
EDIT
There are two methods you can employ:
1. Use a local xml file for your base layout overrides. - app/design/frontend/your_package/your_theme/layout/local.xml
This should really be your preferred method, unless there is a good argument against for your particular use case.
<?xml version="1.0"?>
<layout>
<default>
<reference name="root">
<action method="unsetChild">
<alias>footer</alias>
</action>
</reference>
<reference name="content">
<action method="insert">
<alias>footer</alias>
</action>
</reference>
</default>
</layout>
OR...
2. Copy base layout files
copy app/design/frontend/base/default/layout/page.xml
to app/design/frontend/your_package/yout_theme/layout/page.xml
Find the footer node which be declared as follows (in an untouched page.xml CE 1.7):
<block type="page/html_footer" name="footer" as="footer" template="page/html/footer.phtml">
<block type="page/html_wrapper" name="bottom.container" as="bottomContainer" translate="label">
<label>Page Footer</label>
<action method="setElementClass"><value>bottom-container</value></action>
</block>
<block type="page/switch" name="store_switcher" as="store_switcher" template="page/switch/stores.phtml"/>
<block type="page/template_links" name="footer_links" as="footer_links" template="page/template/links.phtml"/>
</block>
it will be a direct descendant of the root node. Move this whole node so that it becomes a child of the main content node:
<block type="core/text_list" name="content" as="content" translate="label">
<label>Main Content Area</label>
<block type="page/html_footer" name="footer" as="footer" template="page/html/footer.phtml" after=">
<block type="page/html_wrapper" name="bottom.container" as="bottomContainer" translate="label">
<label>Page Footer</label>
<action method="setElementClass"><value>bottom-container</value></action>
</block>
<block type="page/switch" name="store_switcher" as="store_switcher" template="page/switch/stores.phtml"/>
<block type="page/template_links" name="footer_links" as="footer_links" template="page/template/links.phtml"/>
</block>
</block>
Remember to refresh your cache if it is enabled :)
EDIT
To answer the question in the comment regarding block positioning using the second method. You can use the before and after attributes.
i.e.
<block type="page/html_footer" name="footer" as="footer" template="page/html/footer.phtml" after="your_sibling_block_name">
also, depending on the other layout xml you might also have to edit the sibling block and add a before attribute to it i.e. before="footer"
