Better code for Router/Dispatcher?

Hello,

I am trying to implement router/dispatcher for my script. I looked at how phpcake, codeigniter and zend framework work but they were way to complicated to what I needed.

I found a tutorial at http://www.phpaddiction.com/tags/axial/url-routing-with-php-part-one/ which is simple to implement.

I have two types of uri:

category / id / description.html
or
category / subcategory / id / description.html

Example: /videos/funny/234/funny_monkey_dancing.html


What I am trying to do is determine category and subcategory, if there is a subcategory, and then the ID.

The way I am doing it right now doesn't look like the proper way. Is there a better way to do this?


Here is my code from the tutorial with a few modifications.

//$requestURI = explode('/', $_SERVER['REQUEST_URI']);
$requestURI = explode('/', "tms_routing/videos/funny/234/funny_monkey_dancing.html");
$subfolder = "tms_routing";

// Remove the subfolder
if (!$subfolder == "") {
	for($i= 0;$i < sizeof($requestURI);$i++){
		if ($requestURI[$i] == $subfolder){
			unset($requestURI[$i]);
			break;
		}
	}
}

// Map paths
if (is_numeric($requestURI[3])) {
	$array["category"] = $requestURI[1];
	$array["subcategory"] = $requestURI[2];
	$array["id"] = $requestURI[3];
} else {
	$array["category"] = $requestURI[1];
	$array["id"] = 	$requestURI[2];
}
