[Solved] New row every 6 image php loop

On my function below I am trying to make it so for every 6 smiley images gentenrated it will create a new row

I have added bootstrap columns in $link[] but need to be able to create a new row every 6 images

Question how to create a new row every 6 images in function below

PHP Code:

function get_clickable_smileys($image_url, $alias = '') {
    
    // For backward compatibility with js_insert_smiley
    if (is_array($alias))
    {
        $smileys = $alias;
    }
    
    elseif (FALSE === ($smileys = _get_smiley_array()))
    
    {
        return FALSE;
        
    }

    // Add a trailing slash to the file path if needed
    
    $image_url = rtrim($image_url, '/').'/';

    $used = array();

    foreach ($smileys as $key => $val)
    {
        if (isset($used[$smileys[$key][0]]))
        {
            continue;
        }

        $link[] = '<div class="col-lg-4"><a data-toggle="tooltip" data-placement="top" title="'.$smileys[$key][3].'" href="javascript:void(0);" onclick="insert_smiley(\''.$key.'\', \''.$alias.'\')"><img src="'.$image_url.$smileys[$key][0].'" alt="'.$smileys[$key][3].'" class="img-thumbnail" width="100%;" height="'.$smileys[$key][2].'px;" /></a></div>';
        
        $used[$smileys[$key][0]] = TRUE;
    }

    return $link;
} 


There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
