function getValues($dataArray,$strKey="")
{
    global $arrFinalValues;

    if(is_array($dataArray))
    {
        $currentKey = $strKey;
        foreach($dataArray as $key => $val)
        {
            if(is_array($val) && !empty($val))
            {   
                getValues($val,$currentKey.$key."_");
            }
            else if(!empty($val))
            {
                if(!empty($strKey))
                    $strTmpKey = $strKey.$key;
                else
                    $strTmpKey = $key;
                $arrFinalValues[$strTmpKey]=$val;
            }
        }
    }
