Including template footer.tpl.php within another template page.tpl.php I am looking for simple way to include footer.tpl.php that is just html block into another template like page.tpl.php. In Grails/Groovy that is as simple as 

&lt;g:render template="side_menu"/&gt;


Is there a same simple way(preferred no use any panels, custom modules, etc) in Drupal? Thank You
The way to include another .tpl.php file is the include function.

Another idea is to add your footer as a region in the page.tpl.php and assign a region wise theme as defined in Drupal 7 Template (Theme Hook) Suggestions


  region--[region].tpl.php 
  The region template is used when a page region has content, either from the Block
  system or a function like hook_page_build(). Possible region names are determined by the  > theme's .info file.
