I need some help I wanna pass this parameter to a Controller

Passing the variables as one string with seperators is a good idea, but there's another way:

PHP Code:

function test($name){
    $uri_seg = $this->uri->uri_to_assoc();

    foreach($uri_seg as $para){
        // Do something with each of the URI segments passed in here after $name
    }
} 


You can even define a default value for every parameter.
