构建自己的PHP框架--抽象Controller的基类

我们将简单的路由解析和执行，从入口文件public/index.php中移入到框架中。入口文件顿时变得清爽无比～～

但是，去我们的controller里看一下，会看到如下的code：

public function actionView()

{

$body = 'Test body information';

require '../views/site/view.php';

}

难道我们每写一个要去渲染页面的action，都要去找相应路径的view，然后把它require进来。肯定不能这样，所以我们要抽象出一个Controller的基类，实现一个渲染页面的方法，让其他的controller继承，就可以使用相应的方法。

不用说，这个controller的基类肯定要写到框架里。而且也要写两个，一个放在base中，一个放在web中，web中的Controller继承base中的。

先来看在base中的

<?php
namespace sf\base;

/**
 * Controller is the base class for classes containing controller logic.
 * @author Harry Sun <sunguangjun@126.com>
 */
class Controller
{
}

只有一个空类，等待添加内容。

再来看web中的

<?php
namespace sf\web;

/**
 * Controller is the base class for classes containing controller logic.
 * @author Harry Sun <sunguangjun@126.com>
 */
class Controller extends \sf\base\Controller
{
    /**
     * Renders a view
     * @param string $view the view name.
     * @param array $params the parameters (name-value pairs) that should be made available in the view.
     */
    public function render($view, $params = [])
    {
        extract($params);
        return require &#39;../views/&#39; . $view . &#39;.php&#39;;
    }
}

可以看到，我们首先从数组中把变量导入到当前的符号表中，然后引入相应的view页面。

然后，在SiteController，我们只需要这么写就可以了。

<?php
namespace app\controllers;

use sf\web\Controller;

class SiteController extends Controller
{
    public function actionTest()
    {
        echo &#39;success!&#39;;
    }

    public function actionView()
    {
        $this->render(&#39;site/view&#39;, [&#39;body&#39; => &#39;Test body information&#39;]);
    }
}

然后，访问www.Bkjia.com，就可以看到跟之前一样的页面了。

我们来完善一下base中的Controller

<?php
namespace sf\base;

/**
 * Controller is the base class for classes containing controller logic.
 * @author Harry Sun <sunguangjun@126.com>
 */
class Controller
{
    /**
     * @var string the ID of this controller.
     */
    public $id;
    /**
     * @var Action the action that is currently being executed.
     */
    public $action;
}

添加了两个属性，分别来记录当前的controller和action。

然后，我们要在解析router之后，将其赋值，code如下：

<?php
namespace sf\web;

/**
 * Application is the base class for all application classes.
 * @author Harry Sun <sunguangjun@126.com>
 */
class Application extends \sf\base\Application
{
    /**
     * Handles the specified request.
     * @return Response the resulting response
     */
    public function handleRequest()
    {
        $router = $_GET[&#39;r&#39;];
        list($controllerName, $actionName) = explode(&#39;/&#39;, $router);
        $ucController = ucfirst($controllerName);
        $controllerNameAll = $this->controllerNamespace . &#39;\\&#39; . $ucController . &#39;Controller&#39;;
        $controller = new $controllerNameAll();
        $controller->id = $controllerName;
        $controller->action = $actionName;
        return call_user_func([$controller, &#39;action&#39;. ucfirst($actionName)]);
    }
}

然后我们就可以在controller和view中拿到相应的controller名字和action名字了，将view.php修改如下：

<html>
    <head>
        <title>title</title>
    <head>
    <body>
        <?php echo $this->id;?><br/>
        <?php echo $this->action;?><br/>
        <?php echo $body;?>
    </body>
</html>

然后我们就可以看到如下的页面了

有人觉得现在大家都前后端分离了，我们不需要用PHP去render一个页面，只需要返回一个josn字符串就好了，这个就更简单了，在web的Controller中添加一个toJson方法即可

    /**
     * Convert a array to json string
     * @param string $data
     */
    public function toJson($data)
    {
        if (is_string($data)) {
            return $data;
        }
        return json_encode($data);
    }

将SiteController中的actionTest，修改如下：

public function actionTest()

{

$data = ['first' => 'awesome-php-zh_CN', 'second' => 'simple-framework'];

echo $this->toJson($data);

}

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
