Zend Framework loading header and footer issues

Zend Framework Loading page header and footer issues
Zend Framework How do I load the page header and footer?
Because the page header and footer are shared, where should I put it, which class or function to load, and how to assign a value to a variable in the footer of the page.

For advice.

Thank you all first.

Put the page header and footer in the views/scripts, in the layouts with $this->render (' your page ') loaded
