URL Router Try/Catch Block

[punk_runner]

I have the code below working perfectly, but I was wondering if there is a more eloquent way to write this, specifically handling the exceptions...

 

This creates an object of a Router Class that parses my clean URLs into a Controller name, method name and the rest are arguments.

 

So for example: www.domain.com/users/view/profile/bobsmith would route to the Users Controller, and find the viewUsers

method and pass the arguments "profile" and "bobsmith" to it, and the method would take it from there... works great.

 

That explains what this code does. My only question is if there is a cleaner way to handle the exceptions, so I don't have

"throw new exception" written four times. Thoughts? Or is it good to go?

 

 

$rawURL = getPageURL();
$router = new Router($rawURL,$rootDIR);
$controller = $router->getController();
$method = $router->getMethod();
$arguments = $router->getArguments();

try {
// check controller exists and set controller path //
if ((isset($controller) && ($controller != ''))) {
	$controllerPath = APPLICATION_PATH . "controllers/" . $controller . ".class.php";

	// check controller path exists //
	if (file_exists($controllerPath)) {
		    
		// set method name and check method exists //
		if ((isset($method) && ($method != ''))) {
			$methodName = $method . ucfirst($controller);

			if (method_exists($controller, $methodName)) {
			// test it out //
				$test = new $controller();
				$response = $test->$methodName($arguments[0]);
				echo $response;
			}
			else {
				// method_exists failed //
				throw new Exception("That method does not exist foo!");
			}
		}
		else {
			// method was not found in URL //
			throw new Exception("No method name was given foo!");
		}
	}
	else {
		// file_exists failed //
		throw new Exception("That controller does not exist foo!");
	}
}
else {
	// controller was not found in URL //
	throw new Exception("No controller name was given foo!");
}
}
catch (Exception $e) {
// spit it out foo //
echo $e->getMessage();
}

Bump.
