class MY_URI extends  CI_URI {
    
    function __construct()
    {
        parent::__construct();
    }
    
    function my_explode_segments($sUrl)
    {
        $segments = array();
        foreach (explode("/", preg_replace("|/*(.+?)/*$|", "\\1", $sUrl)) as $val)
        {
            if ($val != '')
            {
                $segments[] = $val;
            }
        }
        
        $segments = array_slice($segments, 2);        
        
        $i = 0;
        $lastval = '';
        $retval  = array();
        foreach ($segments as $seg)
        {
            if ($i % 2)
            {
                $retval[$lastval] = $seg;
