Obtener IP del visitante de forma eficiente
En muchas ocasiones necesitamos obtener la IP del visitante para habilitarle según que acciones o simplemente para reconocerlo sin necesidad de que se tenga que registrar y logear para interactuar con la Web.
La siguiente función obtiene la IP del usuario de forma eficiente:
<?php
function getIP() {
if (isset($_SERVER)) {
if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
return $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
return $_SERVER['REMOTE_ADDR'];
}
} else {
if (isset($GLOBALS['HTTP_SERVER_VARS']['HTTP_X_FORWARDER_FOR'])) {
return $GLOBALS['HTTP_SERVER_VARS']['HTTP_X_FORWARDED_FOR'];
} else {
return $GLOBALS['HTTP_SERVER_VARS']['REMOTE_ADDR'];
}
}
}
?>

I am very happy to read this. This is the kind of manual that needs to be given and not the accidental misinformation that’s at the other blogs. Appreciate your sharing this best doc.
Que tal Jose, excelente Blog. Te comento que este codigo en particular no es muy eficiente, ya que te muestra la IP privada. Por tanto, podes tener 100 personas al mismo tiempo en tu website con la misma IP y ninguna forma de diferenciarla.
Un buen punto seria tomar la IP privada y tambien la IP Publica (de esa forma hasta podrias diferencias a 2 personas dentro de una misma LAN que salen por la misma IP).
No es muy dificil obtener la IP Publica, asi que seria una buena opcion.
