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。

在FLEA下面建一個My的目錄里面放自已的類。比如My_Dispatcher_Regexp放在：
My/Dispatcher/Regexp.php
同時為方便寫一個生成網址助手：
My_Helper_Router
My/Helper/Router.php
代碼如下: <?php/*** 路由網址助手*/function rurl($routerName, $urlOptions, $absolute = false) {$routerHelper =& FLEA::getSingleton('My_Dispatcher_Regexp');echo $routerHelper->url($routerName, $urlOptions, $absolute);} 復制代碼 使用方法：
/* 修改默認的Dispatcher為自定義的Dispatcher類*/
FLEA::setAppInf('dispatcher','My_Dispatcher_Regexp');
/* 設置路由配置信息的文件位置*/
FLEA::setAppInf('routerConfig', './APP/config/router.php');
其它代碼跟任何一個普通的例子一樣。
controller里面代碼如下： <?phpclass Controller_Default extends FLEA_Controller_Action{function actionIndex(){FLEA::loadFile('My_Helper_Router');include('APP/View/PostIndex.php');}} 復制代碼 我們在view中用下面代碼： <?phpdump($_GET);rurl('myFirstRouter', array('id' => '33', 'name' => 'thename')); 復制代碼 就可以看到$_GET得到正確的參數，
rurl也生成我們期望的網址:
blog/view/33-thename.html
絕對網址生成方法如下： rurl('myFirstRouter', array('id' => '33', 'name' => 'thename'),true);//將生成如下的網址：/other/fleaphp/test/blog/view/33-thename.html 如果沒有使用apache的mod_rewrite功能生成的網址如下：/fleaphp/test/index.php/blog/view/33-thename.html |
