How to separate an array

[eluser]JayArias[/eluser]
I'm still stuck on parsing this output.

Code:

$this->db->select('tags');
        $this->db->where('aprooved', 'yes');
        $this->db->limit(50);
            $query = $this->db->get('catalog');
            $row = $query->result_array();
            
        print_r($row);

output

Code:

Array ( [0] => Array ( [tags] => business, masters, music, sound, grey ) [1] => Array ( [tags] => green, toro, bull, mens ) [2] => Array ( [tags] => ) [3] => Array ( [tags] => ) [4] => Array ( [tags] => ) [5] => Array ( [tags] => ) [6] => Array ( [tags] => ) [7] => Array ( [tags] => ) [8] => Array ( [tags] => exclimation, person, awesomeness, girl, white, black ) [9] => Array ( [tags] => fishie, grey, blue, tank, tank-top ) [10] => Array ( [tags] => flamingo, love, red, tank-top, tanktop, white, drip ) )
