How can I obfuscate a Symfony PHP Web App?

Question

I am looking to distribute a symfony web app, but don't want to reveal its source code.

I know it is tough to obfuscate PHP, but I was wondering if there are any closed or open source solutions to obfuscate and/or encode the backend code so that someone receiving the app can run it but wouldn't be able to view the source code?

Answer 1

phc (a PHP compiler) has an --obfuscate flag
