Fatal error: Cannot use object of type CI_DB_mysql_result as array

I believe that is the first time that I treat him as an array...

Here is the full code:

Code:

private function _parseResultTree($intParentId,&$arrRows,$intDepth,$intRunner)
     {
        
        // stop at this depth
        if($intDepth == $intRunner)
        {
            return array();
        }
    
        $arrChildren = array();

        for($i=0;$i<count($arrRows);$i++)
        {
            if($intParentId == $arrRows[$i]->parent_id_cat) {
                $arrChildren = array_merge($arrChildren,array_splice($arrRows,$i--,1));
            }
        }
    
        $intChildren = count($arrChildren);
        if($intChildren != 0)
        {
            for($i=0;$i<$intChildren;$i++)
            {
                $arrChildren[$i]['children'] = parse_into_tree($arrChildren[$i]['id_cat'],$arrRows,$intDepth,$intRunner++);
            }        
        }
    
        return $arrChildren;
    
    }

thanks a lot,
