Composer

Composer 可以輕易地解決 PHP 套件下載、安裝、更新、管理等問題。

Composer 之於 PHP 感覺就很像
npm 之於 Node
gem 之於 Ruby
pip 之於 Python

Installation

sudo apt-get install curl # 安裝 curl
curl -sS https://getcomposer.org/installer | php # 產生 composer.phar，然後可以直接執行操作
sudo mv composer.phar /usr/local/bin/composer # 用全域的方式執行就再下這個指令

Mac OSX 出錯的解決方法

Docker

Add the following statement in .bash_profile:

alias composer="docker run -i -t --rm -v \$PWD:/app composer/composer:1.1-alpine"

Default PHP version is 7

Usage

查套件的地方：

https://packagist.org/explore/

Modifying Repositories

Create Package

可以參考 Packagist 首頁說明，和 Composer 語法說明

建立自己的 package，首先要在專案根目錄建立一個 composer.json 檔案：

{
    "name": "your-vendor-name/package-name",
    "type": "library",
    "description": "A short description of what your package does",
    "keywords": ["log","logging"],
    "homepage": "http://example.com",
    "authors": [
        {
            "name": "Jordi Boggiano",
            "email": "j.boggiano@seld.be",
            "homepage": "http://seld.be",
            "role": "Developer"
        }
    ],
    "require": {
        "php": ">=5.3.0",
        "another-vendor/package": "1.*"
    }
}

Use Private Repositories

官方說明

使用 Packagist
使用 Satis 上傳的 repository 記得要標版號，不然就算使用 * 也是找不到的。不過可以用 dev-master 來得到最新的 master。範例
使用 Toran Proxy (Non-free)
