PHP Manual

The Yaf_Router class

(No version information available, might only be in SVN)


Yaf_Router is the standard framework router. Routing is the process of taking a URI endpoint (that part of the URI which comes after the base URL) and decomposing it into parameters to determine which module, controller, and action of that controller should receive the request. This values of the module, controller, action and other parameters are packaged into a Yaf_Request_Abstract object which is then processed by Yaf_Dispatcher. Routing occurs only once: when the request is initially received and before the first controller is dispatched. Yaf_Router is designed to allow for mod_rewrite-like functionality using pure PHP structures. It is very loosely based on Ruby on Rails routing and does not require any prior knowledge of webserver URL rewriting. It is designed to work with a single Apache mod_rewrite rule (one of):

Example #1 Rewrite rule for Apache

RewriteEngine on
RewriteRule !\.(js|ico|gif|jpg|png|css|html)$ index.php
or (preferred):

Example #2 Rewrite rule for Apache

RewriteEngine On
RewriteCond % -s [OR]
RewriteCond % -l [OR]
RewriteCond % -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]
If using Lighttpd, the following rewrite rule is valid:

Example #3 Rewrite rule for Lighttpd

url.rewrite-once = (
  ".*\?(.*)$" => "/index.php?$1",
  ".*\.(js|ico|gif|jpg|png|css|html)$" => "$0",
  "" => "/index.php"
If using Nginx, use the following rewrite rule:

Example #4 Rewrite rule for Nginx

server {
  listen ****;
  root   document_root;
  index  index.php index.html;

  if (!-e $request_filename) {
    rewrite ^/(.*)  /index.php/$1 last;

Default route

Yaf_Router comes preconfigured with a default route, which will match URIs in the shape of controller/action. Additionally, a module name may be specified as the first path element, allowing URIs of the form module/controller/action. Finally, it will also match any additional parameters appended to the URI by default - controller/action/var1/value1/var2/value2.


Module name must be defined in config, considering application.module="Index,Foo,Bar", in this case, only index, foo and bar can be considerd as a module name. if doesn't config, there is only one module named "Index".

Some examples of how such routes are matched:

Example #5 Yaf_Route_Static(default route)example

// Assuming the following configure:
$conf = array(
   "application" => array(
      "modules" => "Index,Blog",

Controller only:
    controller == news
Action only(when defined yaf.action_prefer=1 in php.ini)
    action  == news
Invalid module maps to controller name:
    controller == foo
Module + controller:
    module     == blog
    controller == archive
Module + controller + action:
    module     == blog
    controller == archive
    action     == list
Module + controller + action + params:
    module     == blog
    controller == archive
    action     == list
    sort       == alpha
    date       == desc
