Is there a static code analyzer for PHP files? The binary itself can check for syntax errors, but I'm looking for something that does more, like unused variable assignments, arrays that are assigned into without being initialized first, and possibly code style warnings. Open-source programs would be preferred, but we might convince the company to pay for something if it's highly recommended.
