Composer packages with detection troubles:

Which type of autoload it uses?

Code example of package classes usage that not detected:

unused_scanner /path/to/configuration/file/scanner_config.php --silent
PHP Warning: require_once(/path/to/configuration/file/scanner_config.php): failed to open stream: No such file or directory in /Users/enz/.composer/vendor/insolita/unused-scanner/Lib/Runner.php on line 86
PHP Fatal error: require_once(): Failed opening required '/path/to/configuration/file/scanner_config.php' (include_path='.:') in /Users/enz/.composer/vendor/insolita/unused-scanner/Lib/Runner.php on line 86

Seems like your /path/to/configuration/file/scanner_config.php is wrong
You should create scanner_config.php based on scanner_config.example.php in my repository, put it near project which you want to check and call unused_scanner with full path to your scanner_config.php as argument

I follow the step and please correct me in which area i'm wrong

Step by Step

1. Install composer global require insolita/unused-scanner

2. Ensure ~/.composer/vendor/bin directory declared in $PATH

3. echo $PATH and i dont see ~/.composer/vendor/bin not in my path
4. Add export PATH=$PATH:~/.composer/vendor/bin
5. echo $path and now i have ~/.composer/vendor/bin
6. composer global update and result is nothing to update
7. prepare configuration file, see scanner_config.example.php, i'm copy example.php and rename it to scanner_config.php and put it my project folder
8. run composer dumpautoload in your project directory
9. run unused_scanner /path/to/configuration/file/scanner_config.php
10. Error is Failed to Open Stream

Please guide me @Insolita

7. prepare configuration file, see scanner_config.example.php, i'm copy example.php and rename it to >scanner_config.php and put it my project folder

Just to copy - is not enough. You must modify it for setup valid path to composer.json of your project, vendor directory of your project and list of directories for scanning.

9. /path/to/configuration/file/scanner_config.php - is not a part of command, is just example path, you should change it with real path to location scanner_config.php from step 7 (it may be like /home/www/my_project/scanner_config.php or /var/www/project_name/scanner_config.php)
