制作php的composer包

目录

1、初始化包
2、将代码推送到github远程仓库
3、为写好扩展包打上tag标签标记当前代码版本
4、将包发布到包管理平台

初始化包，生成

    },
    "autoload": {
        "psr-4": {
            "Liuyuanshan11\\Demo\\": "src/"
        }
    },
    "authors": [
        {
            "name": "liuyuanshan"

随后调整composer.json配置文件，内容示例如下：

{
    "name": "liuyuanshan11/demo",
    "description": "this is test project",
    "homepage":"https://github.com/liuyuanshan11/demo",
    "require": {
        "php":">=7.0",
        "ext-json": "*"
    },
    "type": "library",
    "autoload": {
        "psr-4": {
            "Liuyuanshan11\\Demo\\": "src/"
        }
    },
    "authors": [
        {
            "name": "liuyuanshan",
            "email": "1019213039@qq.com",
            "homepage":"https://github.com/liuyuanshan11/demo"
        }
    ],
    "minimum-stability": "dev"
}

编写测试代码
src/Test.php
