creating a hidden dependency on PHP in Java.

Is there a way to create a hidden(to browser) dependency on PHP in Java.

I was thinking something with encrypted key generation. Like a Password that is used to generate a hash on a time stamp that PHP could also do so they can have the same key every 10 seconds or so.

or is there something else super easy.

System.out.print("DONGS"); is valid PHP.
