一、composer依赖包管理工具。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编码规范开发的一套PHP框架，纯面向对象开发，composer依赖包管理、twig模版引擎、Medoo数据库类、Whoops错误输出等......",
"require":{
"twig/twig":"*",
"catfan/medoo":"*",
"filp/whoops":"*"
}
}在项目根目录下使用命令执行 composer install 安装twig、medoo、whoops插件
二、入口文件。index.php 引入vendor/autoload.php文件，开启whoops错误提示插件
<?php
header('Content-type:text/html;charset=utf-8');
date_default_timezone_set('PRC');
require_once(__DIR__.'/configs/Website.php');
require_once(__DIR__.'/frame/Common/Function.php');
require_once(__DIR__.'/frame/App.php');
require_once(__DIR__.'/vendor/autoload.php');
if(DEBUG){
$whoops = new \Whoops\Run;
$whoops->pushHandler(new \Whoops\Handler\PrettyPageHandler);
$whoops->register();
ini_set('display_error','On');
} else {
ini_set('display_error','Off');
}
spl_autoload_register('frame\App::autoload');
frame\App::run();
?>三、数据库配置文件。configs/Database.php
<?php
return array(
'database_type' => 'mysql',
'database_name' => 'redis',
'server' => 'localhost',
'username' => 'root',
'password' => 'root',
'charset' => 'utf8',
'port' => 3306,
'prefix' => 'redis_',
);四、数据库操作类。frame/Libs/Model.php
<?php
namespace frame\Libs;
use frame\Libs\Config;
use Medoo\medoo;
class Model extends medoo
{
public function __construct()
{
$databaseConfigs = Config::get('Database',NULL,TRUE);
parent::__construct($database);
}
}五、模型层操作数据库。app/Models/Users.php
<?php
namespace app\Models;
use frame\Libs\Model;
class Users extends Model
{
public $table = 'users';
//获取用户列表
public function lists()
{
return $this->select($this->table,'*');
}
//增加用户
public function addOne(array $data)
{
return $this->insert($this->table,$data);
}
//删除用户
public function delOne(array $where)
{
return $this->delete($this->table,$where);
}
//修改用户
public function editOne(array $data, array $where)
{
return $this->update($this->table,$data,$where);
}
}六、视图层基类。app/Controllers/Controller.php
<?php
namespace app\Controllers;
class Controller
{
public function view(string $file,array $data = [] )
{
$views = APP.'/Views/'.$file.'.html';
if(is_file($views)) {
$twigConfig = CACHE ? array( 'cache' => 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."视图模版不存在", 1);
}
}
}七、控制器操作数据并显示到页面。app/Controllers/Home/IndexController.php
<?php
namespace app\Controllers\Home;
use app\Controllers\Controller;
use app\Models\Users;
class IndexController extends Controller
{
public function __construct()
{
$this->model = new Users;
}
public function index()
{
//获取所有用户
$users = $this->model->lists();
//删除用户
// $del = $this->model->delOne(['id'=>1]);
//修改用户
// $update = $this->model->editOne(['user'=>'张三'],['id'=>2]);
//视图模版渲染
$this->view('Home/index',['users'=>$users]);
}
}八、视图文件。app/Views/Home/index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>twig模版引擎</title>
</head>
<body>
{% for item in users %}
用户名：{{item.user}} <br>
密码: {{item.pass}} <br>
{% endfor %}
</body>
