用于检测无用文件或无用代码PHP的工具

Question

I have a very big PHP project with i think a lot of useless stuffs .

Do you have some tips or maybe some tools to detect useless part of code or useless files ?

Answer 1

PHP Mess Detector (PHPMD) :

• Possible bugs;
• Suboptimal code;
• Overcomplicated expressions;
• Unused parameters, methods, properties.

PHPMD will show to you all mess created in your code. It's also show the cyclomatic complexity of your codem which will let you do a few code optimizations.

PHP Depend

PHPMD is a spin-off of PHP Depend. PHP Depend will show to you better metrics and graphics of your software than PHPMD. A really powerfull tool, better than PHPMD for optimization, but with a different purpose.

Mark Baker also talked about PHP Dead Code Detector (PHPDCD). IDK the project, but seems very similar to PHPMD.
