Adding activemenu to my own menus

Mmm I have read the README about how to add our own activemenus.
I have build some menus myself in php, but not with the drupal menu functions, just by using html code.

Is it still possible then to add activemenus?

Thanks

EDIT : here is the code of my block :

<?php
// $Id: views-view-list.tpl.php,v 1.3 2008/09/30 19:47:11 merlinofchaos Exp $
/**
 * @file views-view-list.tpl.php
 * Default simple view template to display a list of rows.
 *
 * - $title : The title of this group of rows.  May be empty.
 * - $options['type'] will either be ul or ol.
 * @ingroup views_templates
 */

  $cLink = request_uri();

  print '<div class="content"><ul class="menu">';
  
  $vTitle='Les Mercuriales au quotidien';
  $vLink='les-mercuriales-au-quotidien';
  
  $options = array();
  $options['title'] .= '';

  $options['attributes']['class'] .= ' activemenu-processed';
  if ($cLink == '/'.$vLink) {$options['attributes']['class'] .= ' active';}

  if (($cLink == '/les-mercuriales-au-quotidien') || (substr($cLink,0,14) == '/cotations-du-')):
    print '<li class="expanded last active-trail">'.l($vTitle,$vLink,$options);
  else:
    print '<li class="collapsed last active-trail">'.l($vTitle,$vLink,$options);
  endif;

  print '<ul class="menu">';
  if (($cLink == '/les-mercuriales-au-quotidien') || (substr($cLink,0,14) == '/cotations-du-')):
  foreach ($rows as $id => $row):
    $options = array();
    $working=$row;
    $myarray = explode('</div>',$working);
    $search = preg_match_all('#<span class="field-content">(.*?)<\/span>#s', $working, $match);
    if ($search) {
      $vTitle = $match[1][0];
      $vLink = $match[1][1];
      $search = preg_match('#<a href="\/(.*?)"#s', $vLink, $match);
      if ($search) {
        $vLink = $match[1];
      } 
    }
    $link['title'] = $vTitle;
    $link['href'] = $vLink;
    $options += array(
      'attributes' => array(),
      'html' => FALSE,
    );
    $options['title'] .= '';
   
    if ($cLink == '/'.$vLink) {$options['attributes']['class'] .= ' active';}

    print '<li class="leaf first">'.l($vTitle,$vLink,$options).'</li>';
    
  endforeach;
  endif;
print '</ul></li></ul></div>';
