Categorized gallery - php

Question

I'm trying to make categorized gallery for my blog. So far I've created datebase with tables: photos (photos_id, photos_gal_id, photos_link), galeries (galeries_id, galeries_title, galeries_description), and there are other tables, but not related to this problem (such as users, posts etc).
I've established connection with db through init file:
<?php
class init {
protected $db, $result;
private $rows;
public function __construct(){
$this->db = new mysqli('localhost','root','hhpass','europa');
}
public function query ($sql){
$this->result = $this->db->query($sql);
}
public function rows(){
for($x =1; $x<= $this->db->affected_rows; $x++){
$this->rows[] = $this->result->fetch_assoc();
}
return $this->rows;
}
}?>
Then I get the data from DB through:
class Galeries extends Init {
public function fetchGaleries(){
//query db
$this->query("SELECT photos_id,
photos.photos_gal_id as 'group',
GROUP_CONCAT(photos_link) as link, galeries.galeries_title, galeries.galeries_description, galeries.galeries_id
FROM photos
INNER JOIN galeries
ON galeries.galeries_id=photos.photos_gal_id
GROUP BY photos.photos_gal_id
ORDER BY galeries.galeries_id ASC");
//return
return $this->rows();
}
}
So far it works fine.. when I call this function in seperate file with:
$galeries_a = new Galeries();
$gals_x = $galeries_a->fetchGaleries();
and if I use the
foreach($gals_x as $gals_y){
echo $gals_y['group'];
}
it does fine and lists galeries(categories): 1,2,3,4. Which are the DB-s groups, as defined by query.
NOW, the problem is, how to make the links show up inside these groups (only links that belong to that group).
I know I have to make UL/LI listings in HTML, and that is not the problem, that part works, the problem is the PHP part :)
To sum, it should look like this.
1 First Gallery
Link One
Link Two etc
2 Second Gallery
Link One
Link Two etc
3 Third Gallery
Link One
Link Two etc
4 Fourth Gallery
Link One
Link Two etc
I've tried everything: while, foreach, everything, cannot get it to work properly.
