Page title code imort in template.php

Hello all,

Thnx for the wonderful module!
I m having troubles to find how and where i have to put the code into template.php
This is the instruction from the module:

4. The page title is ultimately set at the theme level. To let your PHPTemplate
   based theme interact with this module, you need to add some code to the template.php
   file that comes with your theme. If there is no template.php file, you can simply
   use the one included with this download. Here is the code:

function _phptemplate_variables($hook, $vars) {
  $vars = array();
  if ($hook == 'page') {

    // These are the only important lines
    if (module_exists('page_title')) {
      $vars['head_title'] = page_title_page_get_title();
    }

  }
  return $vars;
}

  As you can see from the code comment, there are only three important lines
  of code:

  if (module_exists('page_title')) {
    $vars['head_title'] = page_title_page_get_title();
  }

  These lines need to be added to the 'page' hook of the _phptemplate_variables
  function.

  Alternately, you can call page_title_page_get_title() from page.tpl.php
  directly at the place where the title tag is generated.

This is my template.php:

<?php
/**
 * Sets the body-tag class attribute.
 *
 * Adds 'sidebar-left', 'sidebar-right' or 'sidebars' classes as needed.
 */
/*
function phptemplate_body_class($sidebar_left, $sidebar_right) {
  if ($sidebar_left != '' && $sidebar_right != '') {
    $class = 'sidebars';
  }
  else {
    if ($sidebar_left != '') {
      $class = 'sidebar-left';
    }
    if ($sidebar_right != '') {
      $class = 'sidebar-right';
    }
  }

  if (isset($class)) {
    print ' class="'. $class .'"';
  }
}
*/

/**
 * Return a themed breadcrumb trail.
 *
 * @param $breadcrumb
 *   An array containing the breadcrumb links.
 * @return a string containing the breadcrumb output.
 */
function phptemplate_breadcrumb($breadcrumb) {
  if (!empty($breadcrumb)) {
    return '<div class="breadcrumb">'. implode(' ›› ', $breadcrumb) .'</div>';
  }
}

/**
 * Allow themable wrapping of all comments.
 */
/*
function phptemplate_comment_wrapper($content, $type = null) {
  static $node_type;
  if (isset($type)) $node_type = $type;

  if (!$content || $node_type == 'forum') {
    return '<div id="comments">'. $content . '</div>';
  }
  else {
    return '<div id="comments"><h2 class="comments">'. t('Comments') .'</h2>'. $content .'</div>';
  }
}
*/

/**
 * Override or insert PHPTemplate variables into the templates.
 */
function _phptemplate_variables($hook, $vars = array()) {
  switch ($hook) {
    case 'page':
      // These next lines add the required stylesheets file and redefine
      // the $css and $styles variables available to your page template
      $vars['css'] = drupal_add_css($vars['directory'] .'/andreas01.css', 'theme', 'screen, projection');
      $vars['css'] = drupal_add_css($vars['directory'] .'/style.css', 'theme', 'screen, projection');
      $vars['css'] = drupal_add_css($vars['directory'] .'/print.css', 'theme', 'print');
      $vars['styles'] = drupal_get_css();
	  // Add a custom textarea.js-file to the page
	  //$vars['js'] = drupal_add_js($vars['directory'] . '/js/textarea.js', ' theme', 'header', FALSE, $cache );
      break;

	default:
	  break;
  }
  return $vars;
}

/**
 * Returns the rendered local tasks. The default implementation renders
 * them as tabs.

 */
/*
function phptemplate_menu_local_tasks() {
  $output = '';

  if ($primary = menu_primary_local_tasks()) {
    $output .= "<ul class=\"tabs primary\">\n". $primary ."</ul>\n";
  }

  return $output;
}
*/

function phptemplate_menu_tree($pid = 1) {
  if ($tree = menu_tree($pid)) {
  switch ($pid) {
    case 1:
      return "\n<ul class=\"avmenu\">\n". $tree ."\n</ul>\n";
/*
	case (variable_get('menu_primary_menu', 0)):
      return "\n$<ul class=\"links primary-links\">\n". $tree ."\n</ul>\n";
	case (variable_get('menu_secondary_menu', 0)):
      return "\n<ul class=\"links secondary=links\">\n". $tree ."\n</ul>\n";
*/
	default:
      return "\n<ul class=\"menu\">\n". $tree ."\n</ul>\n";
	}
  }
}

function phptemplate_menu_item_link($item, $link_item) {
  return l_curr($item['title'], $link_item['path'], !empty($item['description']) ? array('title' => $item['description']) : array(), isset($item['query']) ? $item['query'] : NULL);
}

function l_curr($text, $path, $attributes = array(), $query = NULL, $fragment = NULL, $absolute = FALSE, $html = FALSE) {
  if ($path == $_GET['q']) {
    if (isset($attributes['class'])) {
      $attributes['class'] .= ' current';
    }
    else {
      $attributes['class'] = 'current';
    }
  }
  return '<a href="'. check_url(url($path, $query, $fragment, $absolute)) .'"'. drupal_attributes($attributes) .'>'. ($html ? $text : check_plain($text)) .'</a>';
}

It would be wonderful to get this working!

I hope someone can help me, i ve got the feeling it isnt really difficult but too difficult for me :)

Thanks,
Jansmale
