①新建一个文件夹，然后在里面按住 shift+右键 打开cmd,输入
> composer init ,然后依次输入信息就会在目录下生成 composer.json如下：
{ "name": "vendor/composer", "require": {} } ②输入 composer install 生成下面vendor目录(用于存放composer包)，然后再文件根目录下创建 index.php作为入口文件并修改内容如下： <?php //引入自动加载文件 require "vendor/autoload.php"; ③创建对应的目录，构建基本的MVC模型目录结构如下：
app目录结构如下：
注：app中routes.php用于存放路由
④为composer.json中 require 添加如下包 "noahbuscher/macaw": "dev-master" ，及修改psr加载目录，完成如下：
{ "name": "vendor/composer", "require": { "noahbuscher/macaw": "dev-master" }, "autoload": { "psr-4": { "App\\": "app/" } } }然后 执行composer udpate 和 composer dump-autoload ，执行完后修改 index.php文件如下：
<?php //引入自动加载文件 require "vendor/autoload.php"; //添加路由 require "app/routes.php";⑤修改app/routes.php文件如下： <?php use \NoahBuscher\Macaw\Macaw; Macaw::get('/', 'App\Controllers\HomeController@home'); Macaw::dispatch();并且新建app/Controllers/HomeController.php文件如下： <?php namespace App\Controllers; class HomeController { public function home() { echo "我是Home文件"; } }然后执行 php -S localhost:8000 运行该项目，并打开浏览器访问结果如下：⑥接下来是引入 数据库连接部分，向composer.json的require添加：
"illuminate/database": "*"
然后cmposer update后修改index.php文件如下：
<?php //引入自动加载文件 require "vendor/autoload.php"; // 引入Eloquent ORM $capsule = new Illuminate\Database\Capsule\Manager(); $capsule->addConnection(require './config/database.php'); $capsule->bootEloquent(); //添加路由 require "app/routes.php";并新建config/database.php文件如下： <?php return [ 'driver' => 'mysql', 'host' => 'localhost', 'database' => 'test', 'username' => 'root', 'password' => 'root', 'charset' => 'utf8', 'collation' => 'utf8_general_ci', 'prefix' => '' ]; ⑦然后新建app/Models/Project.php如下： <?php namespace App\Models; use Illuminate\Database\Eloquent\Model; class Project extends Model { protected $table = 'project'; public $timestamps = false; public function getAll() { return $this->all()->toArray(); } }并修改HomeController.php中的home 方法如下： <?php namespace App\Controllers; use App\Models\Project; class HomeController { public function home() { $model = new Project(); var_dump($model->getAll()); } }注：记得引入对应model，如use App\Models\Project;刷新浏览器结果如下：
⑧引入视图层的模板引擎，向composer.json添加 "xiaoler/blade": "^0.3.1", 然后composer update 更新
并且更新composer.json的psr4如下：
{ "name": "vendor/composer", "require": { "noahbuscher/macaw": "dev-master", "illuminate/database": "*", "xiaoler/blade": "^0.3.1" }, "autoload": { "psr-4": { "App\\": "app/", "Tool\\": "tool/" } } }执行composer dump-autoload，然后新建tool/View.php如下： <?php namespace Tool; use Xiaoler\Blade\Compilers\BladeCompiler; use Xiaoler\Blade\Engines\CompilerEngine; use Xiaoler\Blade\Factory; use Xiaoler\Blade\FileViewFinder; class View { /** * 获取视图 * @return Factory */ public static function getView() { $compiler = new BladeCompiler($_SERVER['DOCUMENT_ROOT'] . '/cache'); $engine = new CompilerEngine($compiler); $finder = new FileViewFinder([$_SERVER['DOCUMENT_ROOT'] . '/app/Views']); $factory = new Factory($engine, $finder); return $factory; } } ⑨新建视图app/Views/home.blade.php如下： <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>{{ $b }}</title> </head> <body> <div>{{ $a }}</div> </body> </html>然后修改HomeController.php如下： <?php namespace App\Controllers; use App\Models\Project; use Tool\View; class HomeController { public function home() { $model = new Project(); //var_dump($model->getAll()); echo View::getView()->make('home', ['a' => '这是aaa', 'b' => 'b是标题'])->render(); } }注：引入use Tool/View
然后刷新浏览器效果如下：
