摘要：框架采用編碼規(guī)范開發(fā)的一套框架，純面向?qū)ο箝_發(fā)，依賴包管理模版引擎數(shù)據(jù)庫類錯誤輸出等在項目根目錄下使用命令執(zhí)行安裝插件二入口文件。引入文件，開啟錯誤提示插件三數(shù)據(jù)庫配置文件。視圖模版不存在七控制器操作數(shù)據(jù)并顯示到頁面。

一、composer依賴包管理工具。composer.json

{
    "name":"PHP-FRAME",
    "author":"Guoming.Zhang",
    "type":"FRAME",
    "version":"v1.0.0",
    "date":"2018-4-16 16:18:00",
    "keywords":["php","frame","PHP框架","MVC"],
    "description":"采用PSR-0編碼規(guī)范開發(fā)的一套PHP框架，純面向?qū)ο箝_發(fā)，composer依賴包管理、twig模版引擎、Medoo數(shù)據(jù)庫類、Whoops錯誤輸出等......",
    "require":{
        "twig/twig":"*",
        "catfan/medoo":"*",
        "filp/whoops":"*"
    }
}

在項目根目錄下使用命令執(zhí)行 composer install 安裝twig、medoo、whoops插件

二、入口文件。index.php 引入vendor/autoload.php文件，開啟whoops錯誤提示插件

pushHandler(new WhoopsHandlerPrettyPageHandler);
    $whoops->register();
    ini_set("display_error","On");
} else {
    ini_set("display_error","Off");
}
spl_autoload_register("frameApp::autoload");
frameApp::run();
?>

三、數(shù)據(jù)庫配置文件。configs/Database.php

 "mysql",
    "database_name" => "redis",
    "server" => "localhost",
    "username" => "root",
    "password" => "root",
    "charset" => "utf8",
    "port" => 3306,
    "prefix" => "redis_",
);

四、數(shù)據(jù)庫操作類。frame/Libs/Model.php


五、模型層操作數(shù)據(jù)庫。app/Models/Users.php
select($this->table,"*");
    }
    //增加用戶
    public function addOne(array $data)
    {
        return $this->insert($this->table,$data);
    }
    //刪除用戶
    public function delOne(array $where)
    {
        return $this->delete($this->table,$where);
    }
    //修改用戶
    public function editOne(array $data, array $where)
    {
        return $this->update($this->table,$data,$where);
    }
}
六、視圖層基類。app/Controllers/Controller.php
 BASEPATH."/storage/cache/" ) : [];
            $loader = new Twig_Loader_Filesystem(APP."/Views/");
            $twig = new Twig_Environment($loader, $twigConfig);
            $template = $twig->loadTemplate($file.".html");
            $template->display($data);
        } else {
            throw new Exception($file."視圖模版不存在", 1);
        }
    }
}
七、控制器操作數(shù)據(jù)并顯示到頁面。app/Controllers/Home/IndexController.php
model = new Users;
    }
    public function index()
    {
        //獲取所有用戶
        $users = $this->model->lists();
        //刪除用戶
        // $del = $this->model->delOne(["id"=>1]);
        //修改用戶
        // $update = $this->model->editOne(["user"=>"張三"],["id"=>2]);
        
        //視圖模版渲染
        $this->view("Home/index",["users"=>$users]);
    }
}
八、視圖文件。app/Views/Home/index.html



    
    twig模版引擎


    {% for item in users %}
        用戶名：{{item.user}} 

        密碼: {{item.pass}} 

    {% endfor %}
