使用composer安装php的相关框架

使用composer来安装php的相关框架，不需要事先准备composer.json以及conmposer.lock以及composer.phar等文件；

直接在项目根目录下是使用composer require frameworkname即可

使用composer require frameworkname命令执行以下动作：

(1)首先在项目根目录下生成composer.json文件

(2)会在项目更目录下生成框架的vendor目录，vendor目录即为框架，vendor目录会包含一个autoload.php文件用于加载框架；包含一个composer目录定义各种加载器

(3)最后生成composer.lock文件

例如在一个空目录下安装beanbun

生成的文件如下所示：

composer.json

{
    "require": {
        "kiddyu/beanbun": "^1.0"
    }
}

autoload.php

<?php

// autoload.php @generated by Composer

require_once __DIR__ . '/composer/autoload_real.php';

return ComposerAutoloaderInitf0360927d4c8cd5f4c7318db461c5f92::getLoader();

composer.lock
