$url         = strip_tags($_SERVER['REQUEST_URI']);
$url_array   = explode("/",$url);

if($url_array[1] == 'admin') //module admin
{  
    include('admin.php'); 
}

$url         = strip_tags($_SERVER['REQUEST_URI']);
$url_array   = explode("/",$url);
 
if($url_array[1] == 'admin') //module admin
{  
    include('admin.php'); 
}
