Composer manages project dependencies

The following tutorial column of composer will introduce you to the dependencies of Composer management projects. I hope it will be helpful to friends in need!

Composer

If you use Composer to manage project dependencies, simply add phpunit/phpunit to the project's composer.json file Dependencies are enough. Here is an example of a minimal composer.json file that only defines a development-time dependency on PHPUnit 5.0:

{
    "require-dev": {
        "phpunit/phpunit": "5.0.*"
    }
}

To complete a system-level installation through Composer, run:

composer global require "phpunit/phpunit=5.0.*"

Please ensure that the path variable contains ~/.composer/vendor/bin/.
