check current page is category page or another page in Magento

 
Hi In magento sometime we need to place conditions on content on the basis of page type .
For  that the best way to find the current page type is to check the controller of that page,
Below you can see how we can do this


  <?php $category = Mage::app()->getFrontController()->getRequest()->getControllerName(); // gives current controller name for eg "cart", "category"

you can check it by
 echo  $category ;  and than on the basis of that you can place your condition like below

in this i have check two controllers cart and or category thats why i have use array to check there values .
    $catpage = array("cart", "category");
if(in_array($category, $catpage)){    ;?>       

        <?php } else { ?>

<?php }?>
