使用DirectoryIterator的简单PHP库

I'm trying to build a simple gallery from a directory. I have this scenario:

- 2013                <-- directory
  -- Album 1          <-- directory
     -- image1.jpg    <-- file
     -- image2.jpg
     -- image3.jpg
  -- Album 2
     -- image1.jpg
- 2014
  -- Album 1
     -- image1.jpg
     -- image2.jpg
  -- Album 2
     -- image1.jpg

I tought that DirectoryIterator can simply do this, but I can't figure out to get it work and call the functions.

So far:

Print a list of years

function listYears(){
$basefolder = "gallery/";
foreach (new DirectoryIterator($basefolder) as $fileInfo) {
    if($fileInfo->isDot()) continue;
    if($fileInfo->isFile()) continue;
    echo '<a href="index.php?year='. $fileInfo->getFilename() .'">'. $fileInfo->getFilename() .'</a><br>';
}
true;
}

Print a list of the Albums in the selected year

function listAlbums($year){
$basefolder = 'gallery/'. $year;
foreach (new DirectoryIterator($basefolder) as $fileInfo) {
    if($fileInfo->isDot()) continue;
    if($fileInfo->isFile()) continue;
    echo '<a href="index.php?year='. $year .'&album='. $fileInfo->getFilename() .'"></a>';
}
true;
}

And finally get the images

function getImages($year,$album){
$basefolder = "gallery/";
foreach (new DirectoryIterator($basefolder) as $fileInfo) {
    if($fileInfo->isDot()) continue;
    if($fileInfo->isDir()) continue;
    echo '<img src="'. $basefolder.''. $year.'/'. $album .'/'. $fileInfo->getFilename() .'">';
}
true;
}

So, i'm trying to do something like

www.site.com/gallery.php?year=2014

and view the albums of 2014, so you can choose

www.site.com/gallery.php?year=2014&album=album_name 

and view the photos from that album.

Even better would be

www.site.com/gallery/2014/album_name

Thank you.

You can use folioGallery It's a php photo gallery which uses your file system to generate gallery.
