这是index.PHP中的代码,只有<?PHP,但没有?>,这是我第一次看到这样的代码,有什么原因吗?
<?PHP // $Id: index.PHP,v 1.94 2007/12/26 08:46:48 dries Exp $ /** * @file * The PHP page that serves all page requests on a Drupal installation. * * The routines here dispatch control to the appropriate handler,which then * prints the appropriate page. * * All Drupal code is released under the GNU General Public License. * See copYRIGHT.txt and LICENSE.txt. */ require_once './includes/bootstrap.inc'; drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL); $return = menu_execute_active_handler(); // Menu status constants are integers; page content is a string. if (is_int($return)) { switch ($return) { case MENU_NOT_FOUND: drupal_not_found(); break; case MENU_ACCESS_DENIED: drupal_access_denied(); break; case MENU_SITE_OFFLINE: drupal_site_offline(); break; } } elseif (isset($return)) { // Print any value (including an empty string) except NULL or undefined: print theme('page',$return); } drupal_page_footer();
