composer 命令实例：

composer 添加一个包作为此项目的依赖项，将其添加到 `composer.json`：

composer require user/package_name

在该项目的 composer.json? 中安装所有依赖项：

composer install

composer 从此项目中卸载一个包，将其作为依赖项从 composer.json 中删除：

composer remove user/package_name

composer 更新此项目的 composer.json 中的所有依赖项：

composer update

将 composer 更新到最新版本：

composer self-update

composer 自动生成对应的类，执行 composer dump-autoload 不会下载任何新内容，而是查找它需要再次包含的所有类。它只是重新生成需要包含在项目中的所有类的列表 autoload_classmap.php：

composer dump-autoload

"autoload": {
    "classmap": [
        "PATH TO YOUR MIGRATIONS FOLDER"
    ],
