function ExtArray($linksArray){
    foreach ($linksArray as $key => $link)
    {
        if ($linksArray[$key] == '' || $linksArray[$key] == NULL || $linksArray[$key] == FALSE || $linksArray[$key] == '')
        {
            unset($linksArray[$key]);
        }else {
            return $linksArray[$key];
        }
    }
