PHP Dead Code Detector (PHPDCD)
===============================

[](#php-dead-code-detector-phpdcd)

**phpdcd** is a Dead Code Detector (DCD) for PHP code. It scans a PHP project for all declared functions and methods and reports those as being "dead code" that are not called at least once.

Limitations
-----------

[](#limitations)

As PHP is a very dynamic programming language, the static analysis performed by **phpdcd** does not recognize function or method calls that are performed using one of the following language features:

- Reflection API
- `call_user_func()` and `call_user_func_array()`
- Usage of the `new` operator with variable class names
- Variable class names for static method calls such as `$class::method()`
- Variable function or method names such as `$function()` or `$object->$method()`
- Automatic calls to methods such as `__toString()` or `Iterator::*()`

Also note that infering the type of a variable is limited to type-hinted arguments (`function foo(Bar $bar) {}`) and direct object creation (`$object = new Clazz`)

Installation
------------

[](#installation)

### PHP Archive (PHAR)

[](#php-archive-phar)

The easiest way to obtain PHPDCD is to download a [PHP Archive (PHAR)](http://php.net/phar) that has all required dependencies of PHPDCD bundled in a single file:

```
wget https://phar.phpunit.de/phpdcd.phar
chmod +x phpdcd.phar
mv phpdcd.phar /usr/local/bin/phpdcd

```

You can also immediately use the PHAR after you have downloaded it, of course:

```
wget https://phar.phpunit.de/phpdcd.phar
php phpdcd.phar

```

### Composer

[](#composer)

Simply add a dependency on `sebastian/phpdcd` to your project's `composer.json` file if you use [Composer](http://getcomposer.org/) to manage the dependencies of your project. Here is a minimal example of a `composer.json` file that just defines a development-time dependency on PHPDCD:

```
{
    "require-dev": {
        "sebastian/phpdcd": "*"
    }
}

```

For a system-wide installation via Composer, you can run:

```
composer global require 'sebastian/phpdcd=*'

```

Make sure you have `~/.composer/vendor/bin/` in your path.
