function scanParentDir(){
    $categories = scandir('categories ');
    foreach($categories as $cat){
        if(file_exists('categories /'.$cat) && $cat != '.' && $cat != '..'){
            changesNamesToSubParentDir($cat);
        }
    }
}

function changesNamesToSubParentDir($cat){
    $albums = scandir('categories /'.$cat);
    foreach($albums as $album){
        if(file_exists('categories /'.$cat.'/'.$album) && $album != '.' && $album != '..'){
            changesNamesToParentDir($album);
        }
    }
}

function changesNamesToParentDir($album){
    $files = scandir('categories /'.$cat.'/'.$album);
    foreach($files as $file){
        if(file_exists('categories /'.$cat.'/'.$album.'/'.$file) && $file != '.' && $file != '..'){
            $filename = pathinfo('categories /'.$cat.'/'.$album.'/'.$file);
            rename('categories /'.$cat.'/'.$album.'/'.$file,     'categories /'.$cat.'/'.$album.'/'.$album.$filename['basename']);
        }
    }
}
?>

Thank you very much.

You can use scandir() (http://php.net/manual/en/function.scandir.php) to get an array of every directory in your "Celebrities" directory.

scandir('path-to-directory');

This will generate an array with all of the directories. After this you can loop through it, and do scandir() again for all of the images.

You can rename the files with rename() (https://www.php.net/manual/en/function.rename.php)

rename('path-to-file<oldname>', 'path-to-file<newname>');

You should really try to code first and ask questions later. Also provide a code sample with what you have already tried.

I hope this works out for you!

EDIT:

These functions will do the trick for you. This is just the basic renaming, you should add more checks and stuff.

<?php

function scanParentDir(){
    $directories = scandir('Categories/Celebrities');
    foreach($directories as $dir){
        if(file_exists('Categories/Celebrities/'.$dir) && $dir != '.' && $dir != '..'){
            changesNamesToParentDir($dir);
        }
    }
}

function changesNamesToParentDir($dir){
    $files = scandir('Categories/Celebrities/'.$dir);
    foreach($files as $file){
        if(file_exists('Categories/Celebrities/'.$dir.'/'.$file) && $file != '.' && $file != '..'){
            $filename = pathinfo('Categories/Celebrities/'.$dir.'/'.$file);
            rename('Categories/Celebrities/'.$dir.'/'.$file,     'Categories/Celebrities/'.$dir.'/'.$dir.$filename['basename']);
        }
    }
}
?>
