Code

function drupal_render_page($page) {
  $main_content_display =& drupal_static('system_main_content_added', FALSE);

  // Allow menu callbacks to return strings or arbitrary arrays to render.
  // If the array returned is not of #type page directly, we need to fill
  // in the page with defaults.
  if (is_string($page) || is_array($page) && (!isset($page['#type']) || $page['#type'] != 'page')) {
    drupal_set_page_content($page);
    $page = element_info('page');
  }

  // Modules can add elements to $page as needed in hook_page_build().
  foreach (module_implements('page_build') as $module) {
    $function = $module . '_page_build';
    $function($page);
  }

  // Modules alter the $page as needed. Blocks are populated into regions like
  // 'sidebar_first', 'footer', etc.
  drupal_alter('page', $page);

  // If no module has taken care of the main content, add it to the page now.
  // This allows the site to still be usable even if no modules that
  // control page regions (for example, the Block module) are enabled.
  if (!$main_content_display) {
    $page['content']['system_main'] = drupal_set_page_content();
  }
  return drupal_render($page);
