As a PHP developer I often find myself having to run executable files installed to a project via Composer (e.g. php-cs-fixer, phpunit, psysh, etc.). These binary files typically reside in vendor/bin relative to the root of a project and in order to run these binary files from the project root I would need to cd into the vendor/bin directory first or type out the relative path (e.g. vendor/bin/php-cs-fixer fix) every time I wanted to run one of these executables.
