3.composer.json 在项目中安装monolog
composer.json文件内容如下

{    "require": {        "monolog/monolog": "1.0.*"    }}

使用composer install 安装,在当前目录下回创建vendor/monolog/monolog 目录
Composer 生成了一个 vendor/autoload.php 文件。你可以简单的引入这个文件,你会得到一个免费的自动加载支持。
这使得你可以很容易的使用第三方代码。项目依赖 monolog,你就可以像这样开始使用这个类库,并且他们将被自动加载。

$log = new Monolog\Logger('name');$log->pushHandler(new Monolog\Handler\StreamHandler('app.log', Monolog\Logger::WARNING));$log->addWarning('Foo');
Copy after login

4:下载thinkphp框架并安装monolog

composer create-project topthink/thinkphp myProjectNamecd myProjectNamevim composer.json

    "require": {        "php": ">=5.3.0",         "monolog/monolog": "1.0.*"    },    找到http://packagist.phpcomposer.com改为https://packagist.phpcomposer.com
Copy after login

保存退出

composer install
Copy after login

在当前目录下回创建vendor/monolog/monolog 目录
可在框架入口文件中引入 vendor/autoload.php
就可在框架中使用了
