How can I perform static code analysis in PHP

Is there a static analysis tool for PHP source 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

There is RIPS - A static source code analyser for vulnerabilities in PHP scripts  The source code of RIPS is available at SourceForge  From the RIPS site   RIPS is a tool written in PHP to find vulnerabilities in PHP applications using static code analysis  By tokenizing and parsing all source code files RIPS is able to transform PHP source code into a program model and to detect sensitive sinks  potentially vulnerable functions  that can be tainted by userinput  influenced by a malicious user  during the program flow  Besides the structured output of found vulnerabilities RIPS also offers an integrated code audit framework for further manual analysis
