Clear templates and cache

Following on from the opcode posting....

One of the little niggles in upgrading Smarty is having to clear the 
templates_c and cache directories.

The following postings by boots and Jan Rosier seem to resolve the 
problem. Could this not go in the official Smarty ??

wishfully thinking

I think this has been on the list before, but anyway here is a example 
howto extend Smarty to do this

<?php

/**
* Template object...
* http://smarty.php.net/
*/
require_once 'Smarty/2.6.3/Smarty.class.php';
class Smarty_Extension extends Smarty
{

     /**
     * Constructor
     *
     * @access   public
     *
     * @return   void
     */
     function Smarty_Extension()
     {
         parent::Smarty();
         $this->checkVersion();
     }

     /**
     * This method checks the current version of Smarty. On different
     * versions the compiled and cached templates are deleted.
     *
     * @access   public
     *
     * @return   void
     */
     function checkVersion()
     {
         $fname = $this->compile_dir . '/.version-' . $this->_version;
         if (!file_exists($fname)) {
             $this->clear_all_cache();
             $this->clear_compiled_tpl();
             touch($fname);
         }
     }

}
$smarty = new Smarty_Extension;

?>
