A框架 第二部 实例化接收到的get类,调用父类抽象方法,自动执行方法call_user_func_array()

01父类抽象类 abstract.php

<?php
abstract class controller_abstract{
protected $app;

function __construct(& $app){
　　$this->app = $app;
}

public function exec(){
call_user_func_array(array($this->app->class,$this->app->action),array($this->app->args));
}

}

02 子类admin.php继承抽象父类前.需要先导入抽象父类abstract.php

<?php
include 'G:/Projects/test/A/apps/system/abstract.php';
class controller_admin extends controller_abstract{
public function __construct($app){
parent::__construct($app);//需要调用父类的构造方法.把获得的参数$_GET全部传递过去
}
public function login(){echo 'please login';

}

}

03子类index.php继承抽象父类前.需要先导入抽象父类abstract.php

<?php
require_once('G:/Projects/test/A/apps/system/abstract.php');
class controller_index extends controller_abstract{

public function index(){

echo 'the index';
}
}

A框架主程序文件--设置$class属性.接收(拼接好的)类名, 通过new 类名()实例化--$this(包含了$_GET接收到的所有参数)

<?php
define('DS','/');
define('A_PATH',str_replace('\\','/',dirname(__FILE__)).DS);

class a {
public $app,$controller,$action,$class,$client;
public function __construct($clien){
$this->client = $clien;
}

public function execute(){

$this->app = $_GET['app'];
$this->controller = $_GET['controller'];
$this->action = $_GET['action'];
$this->args = $_GET;

$this->app_dir = A_PATH .'apps'.DS.$this->app.DS;
$file = $this->app_dir.'controller'.DS.$this->controller.'.php';
require($file);

$this->class = 'controller_'.$this->controller;

$obj = new $this->class($this);

$response = $obj->exec();

}

}
