PHP compiler optimization

Question

For a website in PHP I was searching Php compilers(I know it is parsed).Could'nt find any except HIPHOP from Facebook.I'm not talking about conversion to binary,I am interested in the optimization tasks a compiler performs so that I can optimize my PHP.Like removing extra variables,unused variables,statements inside loops,optimize expressions etc. Are there any such programs available?

First of all, why would you declare variables that are unused? I would suggest that you use an IDE like Netbeans or Eclipse that will highlight any variables that are currently unused. — Daniel

It seems you are searching for PHP optimizers like APC, eAccelerator, Zend Optimizer and others and not for a compiller

No,I am not talking bout APCs,I am just talking bout local code enhancement using a tool like a compiler.APCs cant perform most of the tasks a compiler can.
