Help with Recursion

[gamew0rld]

Alright, I have a function that will take the file name and print the title and a "map" to that page. My code is below.

function display_map($type, $filename){
		if ($filename == ""){
			$fullPath = $_SERVER['REQUEST_URI']; 
			$tmpArray = split("/", $fullPath);
			$count = count($tmpArray);
			$filename = $tmpArray[$count - 1];
		}
		$file = array();
		$title = array();
		$map = array();

	$file[0] = "index.php";
	$title[0] = "Home";
	$map[0] = "a";

	$file[1] = "news.php";
	$title[1] = "News";
	$map[1] = "<a href=\"index.php\">Home</a> > News";

	$file[2] = "games.php";
	$title[2] = "Games";
	$map[2] = "<a href=\"index.php\">Home</a> > Games";

	$file[3] = "games.php?category=1";
	$title[3] = "Action Games";
	$map[3] = "<a href=\"index.php\">Home</a> > Action Games";

	$k = count($file);

	for ($i=0; $i<$k; $i++){
		if ($filename == $file[$i]) 
			if ($type == "map"){
				return $map[$i];
			} else if ($type == "title") {
				return $title[$i];
			}
	}

	display_map($type, basename($_SERVER['PHP_SELF']));
}

It would work fine, however, I have pages that are like games.php?category=1, etc. I have a bunch more pages listed in my script, but I removed them so the script is shorter

Now, the problem is that if for some reason, someone types in the page index.php?, nothing will be displayed because of the ? at the end. I thought that I would be able to call the function again at the end if nothing was returned, and I use the basename() function to strip all the garbage off the filename but for some reason, nothing is returned. I tested it a bunch of times, and everything works fine, but nothing is returned for some reason. Anyone know why? Its late and its probably a small thing, but this is driving me crazy...

Also, am I making this whole thing more complicated than it has to be? Its been a while since I coded...

Thanks in advance.

I should have added that if the recursion does not need to take place (i.e. when the url has no problems), a value is returned, its only when the recursion takes place that no value it returned.

I couldnt figure out why it wouldnt return a value, but I was able to get it to work by changing the for statement to the following:

for ($i=0; $i<$k; $i++){ 
            if ($filename == $file[$i])  

                if ($type == "map"){ 
                    echo $map[$i]; 
                    return;
                } else if ($type == "title") { 
                    echo $title[$i]; 
                    return;
                } 
             } 
}
