subuda remota error geturl

[jumped]

Hola,
estoy intentando realizar una suboda remota a traves de un script en php que me he bajado de internet. He instalado Xampp para que ejecute el php pero me dice el siguiente error cuando lo ejecuto en el navegador a traves de localhost:
________________________
Use Default login/pass.
Login to lolabits.es

Fatal error: Call to undefined function geturl() in C:\xampp\htdocs\lolabits\lolabits.es.php on line 43
__________________________

Este es el código: (esta en negrita la linea)
Un saludo.
