安装

$ sudo php -r "readfile('https://getcomposer.org/installer');" | php$ sudo mv composer.phar /usr/local/bin/composer

使用

以 为例，先看一下他的composer.json文件的内容：

{    "name": "mikecao/flight",    "description": "Flight is a fast, simple, extensible framework for PHP. Flight enables you to quickly and easily build RESTful web applications.",    "homepage": "http://flightphp.com",    "license": "MIT",    "authors": [        {            "name": "Mike Cao",            "email": "mike@mikecao.com",            "homepage": "http://www.mikecao.com/",            "role": "Original Developer"        }    ],    "require": {        "php": ">=5.3.0"    },    "autoload": {        "files": [ "flight/autoload.php", "flight/Flight.php" ]    },    "require-dev": {        "phpunit/phpunit": "~4.6"    }}

注意 autoload。

$ cd /var/www/html$ touch index.php$ touch .htaccess

.htaccess内容如下：

    
         RewriteEngine on    RewriteBase /    RewriteRule !\.(js|html|ico|gif|jpg|png|css)$ index.php
    

下载flight:

$ composer require mikecao/flight

看下目录结构：

和index.php同一级的composer.json的内容如下：

{    "require": {        "mikecao/flight": "^1.2"    }}

编写index.php：

浏览器访问http://127.0.0.1、http://127.0.0.1/foo可以看到效果。

修改composer.json后

$ composer install# 或者$ composer update
