开发属于自己的composer

1.新建一个git仓库
备注：可以在github建立，如果要建立私有的composer，可以自己搭建git仓库

2.初始化composer文件
执行composer init
参考：https://getcomposer.org/doc/04-schema.md
{
    "name": "joyousphper/composer-demo",
    "description": "composer demo",
    "type": "library",
    "license": "MIT",
    "authors": [
        {
          "name": "joyousphper",
          "email": "joyousphper@gmail.com"
        }
    ],
    "minimum-stability": "stable",
    "require": {
        "php": ">=5.4.0"
    },
    "autoload": {
        "psr-4": {
          "Tools\\": "src/Tools/"
        }
    }

}

3.编写代码并推送git仓库
新建src/Tools/Common.php
<?php
namespace Tools;

class Common
{
    public static function demo()
    {
        return 'hello world';
    }

}
添加标签
git tag -a v0.1.1 -m'第二个版本'
git push origin tag v0.1.1

4.提交composer
https://packagist.org/packages/submit

5.查看提交composer包
https://packagist.org/packages/joyousphper/composer-demo

6.设置composer自动更新
6.1打开https://github.com/JoyousPHPer/composer-demo/settings/installations添加一个Packagist服务
6.2https://github.com/JoyousPHPer/composer-demo/settings/hooks设置hook，这里的apitoken可以从https://packagist.org/profile/查看

7.项目引用
{
    "name": "joyousphper/demo1",
    "description": "composer demo",
    "type": "project",
    "license": "MIT",
    "authors": [
        {
          "name": "joyousphper",
          "email": "joyousphper@gmail.com"
        }
    ],
    "minimum-stability": "dev",
    "require": {
        "joyousphper/composer-demo": "v0.1.*"
    }
}

8.使用案例
<?php
require __DIR__ . '/../vendor/autoload.php';
use Tools\Common;

echo Common::demo();
