I am just learning the zend framework and i know this is a very basic question. I have created a layout and it is working fine. My layout is something like following


<?php echo $this->layout()->header; ?>

<?php echo $this->layout()->content; ?>

<?php echo $this->layout()->footer; ?>


my question is where will i define $this->layout()->header? is this a simple phtml file or do i need to write any class? Also if it is a simple phtml file where do i store it? In the same directory of layout file or any other directory?
