PHP Using Composer

說明
Php Plugins 須透過 Composer 安裝，
如果只是把 source 放在資料夾裡，伺服器不會去找來用，


安裝流程
1. download Composer 
2. clone composer、composer.bat、composer.phar 三個檔案到 專案資料夾
3. 製作 composer.json 檔案
以 reCatcha 例為
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": "2.*",
    "zendframework/zendservice-recaptcha": "2.*"

    }
4. 執行 cmd => php composer.phar install
