URL Manipulation

$a = $_SERVER['HTTP_HOST'] // server-name - domain
$b = $_SERVER['PHP_SELF'] // you're page, as you know
$c = $_SERVER['QUERY_STRING'] // everything after the "?",
// but not including the "?"

echo "$a$b?$c";  // would print whole URL

$d = $_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']."?".$_SERVER['QUERY_STRING'];
// notice the "?" in middle of the above, and variables seprated by dots(.)
// $_SERVER['QUERY_STRING'] reads url GET query, but does not contain
// the "?" in it itself, since "?" is not a variable.

echo $d; // would print the whole URL using above.

Registrar variables globales

/**
* Registrar variables globales
*
* Esta funcion toma valores del espacio global $HTTP_*_VARS desde un array
* en la llamada a la funcion, y si existen y tienen contenido, las registra
* como globales para que puedan ser accedidas a continuación.
* Debe recibir una lista de elementos en la llamada a la funcion.
* El primero de estos valores deberá ser el método desde el que obtener
* los valores para las variables (GET, POST, COOKIE, SESSION, FILES, ENV, o SERVER).
* El resto de elementos de la lista son los nombres de las variables que
* deberíamos de haber recibido.
*
* P.ej.:
* $nombre_clase->registraParametro(GET,nombre,password)
* haria lo siguiente:
*    $nombre = $_GET['nombre'];
*    $password = $_GET['password'];
*    global $nombre,password;
*
