Hola de antemano saludos, tengo un problema en un proyecto de la uni, tengo un formulario en php que al meterle 3 números me los debe permutar (solo me mostrara las 6 opciones principales de la ´permuta) y mostrar en un textarea y a la vez guardarlos en la base de datos, les pongo los códigos ´para que le echen un vistazo.....
la verdad que al apretar el boton solo realiza el proceso de permuta pero no melo guarda ala base de datos...

* Description: The intent of this permutation generator is to
* describe in simple terms how to change the order or arrangment of
* the characters in a string... in other words, it's a teaching tool.
* It employs a "hold-one-character-constant-while-rearranging-the-remaining-characters-using-a-recursive-function"
* technique. This is by no means the "best" or "fastest" way of calculating
* permutations (*is* there a best way?). It's sorta fast, but JavaScript
* code is not well known for setting speed records. To understand the algorithm,
* one should be familiar with looping, arrays, pushing, popping, and recursion.
* If you can say, "I haven't had 'arrays' yet", well -- I haven't had a raise in
* a while either... so go pick up a book or take a Computer Science class
* (like CS161) and when you're done this'll all make more sense.
