php - Building a URL rules map for MVC Framework -

-

i have built own php mvc framework after following tutorials online. have working using entry script in .htaccess follows:

rewriteengine on  rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d  rewriterule ^(.*)$ index.php?rt=$1 [l,qsa]

i have router class translates url , divides in action / controller segments:

$route = (empty($_get['rt'])) ? '' : $_get['rt'];  if (empty($route)) {     $route = 'index'; } else {     /*** parts of route ***/     $parts = explode('/', $route);     $this->controller = $parts[0];      if(isset( $parts[1]))     {         $this->action = $parts[1];     } }

what want take 1 step further , define url rewriting rules work in addition automatic routing. want able this:

$rules = array(     'directory/listing/<id>' => 'listing/index',     'directory/<category>/<location>' => 'directory/view', );

in above, array key entered url - parts in angle brackets dynamic variables (like variables). array value request needs routed (controller/action). above 2 rules have following 2 actions:

public function actionindex($id) { }  public function actionview($category, $location) { }

so url needs checked against array keys first, if matches 1 of keys needs use array value controller/action pair.

anybody have ideas how go this?

i'm not sure of exact code need implement in environment, can mention how magento's url rewrites function. urls structured <controller>/<action>/<arguments>. take 1 step further , define key/value pairs url parameters ../id/20/meta/25 turns array so:

array(     'id' => 20,     'meta' => 25 )

you download source , check out. may head in right direction:
