function loadClasses($dir) {
    $d = new \DirectoryIterator($dir);
    while($d->valid()) {
        $f = $d->current();
        if($f->getExtension() == 'php') {
            include $f->getPathname();
        } elseif($f->isDir()&&!$f->isDot()) {
            loadClasses($f->getPathname());
        }
        $f->next();
    }
