symfony2 安装并创建第一个页面,symfony2第一个_PHP教程
symfony2 安装并创建第一个页面,symfony2第一个
1、安装和配置
参考 http://symfony.cn/docs/book/installation.html
使用安装工具:
windows系统
Open your command console and execute the following command:
c:\> php -r "readfile('http://symfony.com/installer');" > symfony.phar
Then, move the downloaded symfony.phar
file to your projects directory and execute it as follows:
c:\> move symfony.phar c:\projects
c:\projects\> php symfony.phar
创建symfony应用:
Once the Symfony Installer is ready, create your first Symfony application with the new
command:
# Linux, Mac OS X
$ symfony new my_project_name
# Windows
c:\> cd projects/
c:\projects\> php symfony.phar new my_project_name
运行symfony应用:
Symfony leverages the internal web server provided by PHP to run applications while developing them. Therefore, running a Symfony application is a matter of browsing the project directory and executing this command:
$ cd my_project_name/
$ php app/console server:run
2、目录
/app:存在缓存、配置文件、日志及核心配置参数;
/bin:存放用到的执行文件;
/src:自己编写的源代码;视图文件放在view文件夹下
/vendor:存放第三方代码;
/web/app.php:单一入口文件
检查配置:
命令行 d:\symfony2.3\app>php check.php或 浏览器输入http://localhost:8000/config.php
3、编写一个hello world页面
>php app/console generate:bundle 创建一个新的bundle
Controller/DefaultController.php
php namespace Test\WebBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template; class DefaultController extends Controller { /** * @Route("/hi/{name}") * @Template() */ //以上注释并不是没有用,是利用注释动态影响程序代码.@Template()使用默认视图文件 public function indexAction($name) {
//$name的值为路由{}中name的值 return array('name' => $name);//返回name的值给视图文件 } }
Default/index.html.twig
Hello {{ name }}!
浏览器中输入http://localhost:8000/app_dev.php/hi/world,页面中可以打印出Hello world!
