用于改变URL的PHP​​交换机案例

Question

I'm building a site on the CodeIgniter framework and I'm using PHP switch to load the specific javascript relevant to the page. My issue comes when I get to the 3rd URI segment, which is generally a variable. for instance I have no issue with say

case 'foo/bar':

but what if my url was something like http://mysite.com/foo/bar/1234, where the 1234 if a variable passed to the controller. It obviously wouldn't make sense to write out a case for every single variable because there's about 30k right now.

currently here's a working snippet of my code...

switch( $this->uri->uri_string() ) {

            case '': 

            break;

            case 'browse':

            break;

            case 'contest/leaderboard':

You could also explode the url on the forward slash and then check each element of an array.

for example

$url_parts = explode('/', $this->uri->uri_string());
switch($url_parts[0]){
  case 'foo':
     if(count($url_parts) > 1){
       if($url_parts[1] == "bar"){
         // when the url begins with foo/bar
       }
     }
     break;
   case 'browse':
     //when url is browse
   break;
}

The benefit of this is you could include code common to all urls that begin with foo. Not sure if this is required but could be useful possibly
