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
{
"_readme": [
"This file locks the dependencies of your project to a known state",
"Read more about it at https://getcomposer.org/doc/01-basic-usage.md#composer-lock-the-lock-file",
