PHP Language Change: Change application language using arrays of text

This is a simple class that can change application language using arrays of text.

It can check if a cookie is set to determine the current language to be used for the texts in a site. If the cookie is not set, the class redirects the current request to access a script that sets the language cookie.

When the language cookie is set the class can load a script that defines an array with texts for the application to use in the language that was set.

In Spanish:

Este script puede cambiar el idioma de algunas palabras de tu pagina en tomando como parametro el valor de una cookie. Devuelve un array con las palabras en el idioma preferido.
