php创建composer组件

1.配置composer.json

在根目录下执行

[root@localhost composer_test]# composer init 
Package name (<vendor>/<name>) [root/composer_test]: xingxing5511001001/name #包的名字
Description []: this is test #描述
Author [, n to skip]:xxx <xxx@qq.com>  #作者邮箱
Minimum Stability []:dev  #包的版本
Package Type (e.g. library, project, metapackage, composer-plugin) []: 
License []: MIT #版权
{
    "name": "xingxing5511001001/name",
    "description": "this is test",
    "license": "MIT",
    "authors": [
        {
            "name": "xxxx",
            "email": "xxxx@qq.com"
        }
    ],
    "require": {}
}

或者手动创建composer.json

{
    "name": "xingxing5511001001/hello",
    "description": "this is test",
    "license": "MIT",
    "authors": [
        {
            "name": "xxxx",
            "email": "xxx@qq.com"
        }
    ],
    "minimum-stability": "dev",
    "require": {
        "php": ">=7.0.0"
    },
    "autoload": {
        "files": [
            "src/p.php"
        ],
        "psr-4": {
            "hello\\": "src/"
        }
    }
}

2.根目录下创建src目录并创建Hello.php,p.php

Hello.php

<?php
namespace hello;
class Hello {
    public static function world()
    {
        echo "hello";
    }

}

p.php

<?php
if (!function_exists('p')) {
    function p($str) {
       
        echo $str;
    }
}

3.安装

在根目录下执行，composer install 会生成vender目录与composer.lock文件

composer install

4.验证是否成功,能正常输出hello则表示OK

根目录创建test.php

ini_set('display_errors',1);
error_reporting(-1);
require_once __DIR__ . '/vendor/autoload.php';
use hello\Hello;
echo Hello::world()."\n";
p("hello");
echo "\n";

5.把composer包发布到# Packagist

5.1先把composer包的代码部署到github
先删除前面测试生成的代码

rm -rf composer.lock
rm -rf test.php
rm -rf vendor
