1,?支持非rewrite即： http://localhost/index.php/blog/view/5456-asdf.html 也可以被正確解析。。 ----------------------------------- 2,增加：絕對地址生成 只要? rurl('myFirstRouter', array('id' => '33', 'name' => 'thename'), true); 最后多加一個true，默認為false即相對地址。 生成絕對地址如：網站根目錄/fleaphp/test/blog/view/33-thename.html 修改自ZendFramework的Router_Regexp類。 花了點時間整理的，水平有限，希望有高人能完善一下。 定義一個路由跟定義DSN一樣的方法： return array( 'routers' =>array( ??'myFirstRouter' => array( ? ?'blog/view(?:/(\d+)-(.+))\.html', ? ?array( ? ? 'id'? ?=> '1', ? ? 'controller'??=> 'default', ? ? 'action'??=> 'index' ? ?), ? ?array( ? ? 1 => 'id', ? ? 2 => 'name' ? ?), ? ?'blog/view/%d-%s.html' ??), ??'mySecondRouter' => array( ? ?'blog(?:/(\d+)-(.+))\.html', ? ?array( ? ? 'id'? ?=> '1', ? ? 'controller'??=> 'default', ? ? 'action'??=> 'index' ? ?), ? ?array( ? ? 1 => 'id', ? ? 2 => 'name' ? ?), ? ?'blog/%d-%s.html' ??), ??'myThirdRouter' => array( ? ?'([a-z0-9]+)/([a-z0-9]+)', ? ?array(), ? ?array( ? ? 1 => 'controller', ? ? 2 => 'action' ? ?), ? ?'blog/%d-%s.html' ??)?? ) ); 復制代碼 是一個二維數組，每一個值為一條路由規則。 其中第一項是正則表達式，第二項為：參數默認值（這里可以設置controller,action,及其它參數的默認值。） 第三項為：參數的對應關系，與第一項的正則表達里面匹配元素對應。 第四項用于生成鏈接時候使用的格式。如果沒看明白，可以看ZF的Router一節。 先發改的My_Dispatcher_Regexp類的代碼： <?php /** * Zend Framework * * LICENSE * * This source file is subject to the new BSD license that is bundled * with this package in the file LICENSE.txt. * It is also available through the world-wide-web at this URL: * http://framework.zend.com/license/new-bsd * If you did not receive a copy of the license and are unable to * obtain it through the world-wide-web, please send an email * to license@zend.com so we can send you a copy immediately. * * @package? ?
