Whats wrong here?

class Config {
    public static function get($path = null) {
        if($path) {
            $config = $GLOBALS['config'];
            $path = explode('/', $path);

            foreach($path as $bit) {
                if(isset($config[$bit])) {
                    $config = $config[$bit];

            return $config;


        return false;

I don't really think there is enough information here to help. How is the class being extended, what makes you think something is wrong? Is it returning $config?, What is $GLOBALS['config'] set to?
