Need help with "segmenting" URI

[eluser]John_Betong_002[/eluser]
I have something similar on a website:


1. fallthrough/last route is set to $route["(:any)"] = "homepage/get_client/$1";
2. class homepage->get_client() checks $this->uri->segment(3)
3. search database->table->clients
4. if valid client return with client's data else return NULL
5. class homepage->get_client()->result either view results or default search page
