How to separate an array

[eluser]Twisted1919[/eluser]

Code:

$tags = array();
foreach( $row as $tag)
{
$tags[] = explode(',',$tag['tags']);//gets only the word
}
//now you have the $tags array which contains arrays with your tags
$out = '';
foreach($tags AS $tag)
{
   if(is_array($tag))
   {
    foreach($tag AS $t)
    {
     $out.= '<a href="'.site_url('search/tag/'.$t).'">#'.$t.'</a>, ';
    }
   }
}
echo $out;

Should work, not sure though.
