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:<span class="se">\> php -r <span class="s2">"readfile('http://symfony.com/installer');" > symfony.phar
</span></span>

Copy after login

Then, move the downloaded <span class="pre">symfony.phar</span> file to your projects directory and execute it as follows:

c:<span class="se">\> move symfony.phar c:<span class="se">\projects
c:<span class="se">\projects<span class="se">\> php symfony.phar</span></span></span></span>

Copy after login

创建symfony应用：

Once the Symfony Installer is ready, create your first Symfony application with the <span class="pre">new</span> command:

<span class="c"># Linux, Mac OS X
<span class="nv">$ symfony new my_project_name

<span class="c"># Windows
c:<span class="se">\> <span class="nb">cd projects/
c:<span class="se">\projects<span class="se">\> php symfony.phar new my_project_name
</span></span></span></span></span></span></span>

Copy after login

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:

<span class="nv">$ <span class="nb">cd my_project_name/
<span class="nv">$ php app/console server:run
</span></span></span>

Copy after login

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

<?<span>php

namespace Test\WebBundle\Controller;

</span><span>use</span><span> Symfony\Bundle\FrameworkBundle\Controller\Controller;
</span><span>use</span><span> Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
</span><span>use</span><span> Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;

</span><span>class</span> DefaultController <span>extends</span><span> Controller
{
    </span><span>/*</span><span>*
     * @Route("/hi/{name}")
     * @Template()
     </span><span>*/</span>
    <span>//</span><span>以上注释并不是没有用，是利用注释动态影响程序代码.<span>@Template()</span>使用默认视图文件</span>
    <span>public</span> <span>function</span> indexAction(<span>$name</span><span>)
    {<br />　　　　 <span>//$name的值为</span><span>路由{}中name的值</span>
        </span><span>return</span> <span>array</span>('name' => <span>$name</span><span>);//返回name的值给视图文件
    }
}</span>

Copy after login

Default/index.html.twig

Hello {{ name }}!

Copy after login

浏览器中输入http://localhost:8000/app_dev.php/hi/world，页面中可以打印出Hello world！
