PHP source code differentiation platform MVC structure introduction
This article mainly introduces the MVC structure of the PHP source code differentiation platform. It has a certain reference value. Now I share it with you. Friends in need can refer to it.
Main:
Model singleton factory
Directory structure optimization
Differentiate platforms (frontend, backend....)

Model Singleton Factory
Preparation: Create branch
1 $ git checkout master 2 $ git checkout -b "folder-model-app"
Instructions:
1) 3 lines in the program. . . Indicates omitted code. You can view
from the front or from the source code 2) [XXX/XXX] indicates the relative path of the project file
Idea:
Problem: Model in the project To operate a data table, one action may require operating the database once and requesting multiple actions at a time. Each action needs to instantiate the corresponding model
Solution idea: Create a model class singleton factory
Implementation: Create a singleton model class FactoryModel.class.php
Attribute $model=array(); Store model class instance
Method: M($cmodelName, array $conf=null) Instantiate model class
Use : Use the model class instance in the controller: $model=FactoryModel::M('Model name')
Code implementation
1) Create a model singleton factory【 Frame/FactoryModel.class.php】
1 <?php
2 /**
3 * 单例模型工厂类
4 * User: young
5 */
6
7 class FactoryModel
8 {
9 protected static $model = array(); //存储模型类实例
10
11 /**
12 * 构造方法
13 */
14 protected function __construct()
15 {
16 }
17
18 /*
19 * 传递一个模型类的类名，就返回该类的一个单例实例对象
20 *@param string $modelName 模型类的类名
21 *@param array $conf 数据库配置信息
22 *@return object 传入模型类的实例（单例）
23 */
24 public static function M($modelName, array $conf=null)
25 {
26 $modelName = $modelName.'Model';
27 if(empty(static::$model[$modelName]) || !(static::$model[$modelName] instanceof $modelName)){
28 static::$model[$modelName] = new $modelName($conf);
29 }
30 return static::$model[$modelName];
31 }
32 }2) Introduce the class file【index.php】
1 <?php 2 /** 3 * 入口文件 4 */ 5 require_once 'Frame/Db.class.php'; //数据库操作类 6 require_once 'Frame/BaseModel.class.php'; //基础模型类 7 require_once('Model/UserModel.class.php'); 8 9 require_once 'Frame/FactoryModel.class.php';//模型工厂类 10 。。。 11 。。。 12 。。。
Entry file introduces the factory model class
3) Application: Used in controllers, such as login operations in user controller UserController [Controller/UserController.class.php]
1 <?php
2 /**
3 * UserController.class.php 用户控制器
4 */
5
6 class UserController extends BaseController{
7 。。。
8 。。。
9 。。。
10
11 /**
12 * 登录操作： 校验登录信息
13 */
14 public function dlogin()
15 {
16 //接收登录信息17 $data = array();
18 $data['username'] = trim($_POST['username']);
19 $data['pwd'] = trim($_POST['pwd']);
20
21 //实例化模型，调用模型方法
22 //$model = new UserModel();
23 //$result = $model->checkLoginInfo($data);
24 //替换上面两行
25 $result = FactoryModel::M('User')->checkLoginInfo($data);
26
27 //跳转提示
28 if($result){
29 $this->msg('登录成功！', '?a=index',3);
30 } else {
31 $this->msg('用户名或密码不正确！！');
32 }
33 }
34 }4) Test program running, http://www.test.com/ blog/index.php The login test results are consistent with the previous ones. Submit the code for the time being
1 git add - 2 git commit -m "完成模型工厂类"
Directory structure optimization
Ideas
Multiple platforms (modules): front and back, backend
MVC structure sub-platform
C: Controllers/Home Controllers/Admin .....
V: Views/Home Views/Admin .....
M: Operation Data Table General Module Common Public Resource Directory Public Public Public Public Public Public Public Public Public Public Public Public Public Public Public Public Public Public Public Public Public Public Public that Public Resource Directory Public Public Public ： Public/Home Public/Admin .....
The directory structure changes, and the paths of all loaded classes and views change accordingly
Code implementation
1) Operation steps1）目录构建: step 1: 根目录下创建目录App, 将Model目录，View目录，Controller目录放大App目录下 既根目录只有： App/ Public/ Frame/ index.php step 2: 在Controller目录中，创建Back目录和Home目录。将UserController控制器类文件放入Home目录中 step 3: 在View目录中，创建Back目录和Home目录。将login.html文件放入Home目录中 step 4: 在Public目录中，创建Back目录，Home目录，Plugins目录。将js,images,css目录放入Home目录中，公共插件放入对应的Plugins目录中 2）文件引入修改： step 5: index.php入口文件对UserCotroller类的引入路径修改 step 6：UserController类中对视图login.html的include路径的修改 step 7: 视图login.html中对css和js路径的引入
Operation step ideas
2) Specific code modification operations Entry file introduction class path modification [index.php] Mainly It is the introduction and modification of the user model class and user controller class path1 <?php 2 /** 3 * 入口文件 4 */ 5 require_once 'Frame/Db.class.php'; //数据库操作类 6 require_once 'Frame/BaseModel.class.php'; //基础模型类 7 require_once 'App/Model/UserModel.class.php'; 8 9 require_once 'Frame/FactoryModel.class.php';//模型工厂类 10 11 require_once 'Frame/BaseController.class.php'; //基础控制器类 12 require_once 'App/Controller/Home/UserController.class.php'; 13 14 //实例化控制器 15 $userCtr = new UserController(); 16 17 $a = !empty($_GET['a']) ? $_GET['a'] : 'login'; 18 19 $userCtr -> $a();
Modification of the entrance file introduction class
The modification of the login form view path introduced by the user controller class【 App/Controller/Home/UserController.class.php】 1 <?php
2 /**
3 * UserController.class.php 用户控制器
4 */
5
6 class UserController extends BaseController{
7 /**
8 * 展示登录界面
9 * @access public10 */
11 public function login()
12 {
13 include "App/View/Home/User/login.html";
14 }
15 。。。
16 。。。
17 。。。User controller display login interface modification
Login form view【App/View/Home/User/ login.html] Modification of static resource path 1 <!DOCTYPE html>
2 <html lang="zh-CN">

15 var form = layui.form;
16 });
17 </script>
18 </body>
19 </html>Login form view
Effect and submission code
Submit and save code
1 git add -A 2 git commit -m "目录结构优化"
Ideas
Implement different operations according to different platforms The user clicks on the page request and sends 3 parameters along with the url: p=Platform&c=Controller&a=Action You can know by receiving the get data in the entry file: Platform, Controller, Action
Code implementation
1) Operation steps:1）入口文件平台区分：
step 1: 入口-登录页面提交的action="?p=Home&c=User&a=dlogin"
step 2: 入口文件index.php 接收$_GET
step 3: 登录判断成功跳转地址： $this->msg('登录成功！', '?p=Admin&c=Index&a=index',3);
2) 后台首页：
step 1: 静态css,js,img文件放置 Public/Admin/
step 2: 创建后台首页控制器类，
index() 载入后台首页视图文件
step 3: View/Admin/Index/index.html 修正css等静态文件路Operation step ideas
2) Login form submission action =“?p=Home&c=User&a=dlogin” [App/View/Home/User/login.html]1 <!DOCTYPE html> 2 <html lang="zh-CN"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>登录</title> 6 <link rel="stylesheet" type="text/css" href="public/plugins/layui/css/layui.css"> 7 <link rel="stylesheet" type="text/css" href="public/Home/css/style.css"> 8 </head> 9 <body> 10 <p class="container"> 11 <p class="content"> 12 <form action="?p=Home&c=User&a=dlogin" class="layui-form" method="post"> 13 。。。。。。。
Login form form submission action modification
3 ) Entry file distinguishes the platform [index.php]<?php /** * 入口文件 */ $p = !empty($_GET['p']) ? $_GET['p'] : 'Home'; //平台 $c = !empty($_GET['c']) ? $_GET['c'] : 'User'; //控制器 $a = !empty($_GET['a']) ? $_GET['a'] : 'login'; //动作 require_once 'Frame/Db.class.php'; //数据库操作类 require_once 'Frame/BaseModel.class.php'; //基础模型类 require_once 'App/Model/UserModel.class.php'; require_once 'Frame/FactoryModel.class.php';//模型工厂类 require_once 'Frame/BaseController.class.php'; //基础控制器类 require_once 'App/Controller/'.$p.'/'.$c.'Controller.class.php'; $ctr = $c."Controller";//实例化控制器 $userCtr = new $ctr();$userCtr -> $a();
1 <?php
2 /**
3 * UserController.class.php 用户控制器
4 */
5
6 class UserController extends BaseController{
7 。。。
8 。。。
9 。。。
10 /**
11 * 登录操作： 校验登录信息
12 */
13 public function dlogin()
14 {
15 //接收登录信息
16 $data = array();
17 $data['username'] = trim($_POST['username']);18 $data['pwd'] = trim($_POST['pwd']);
19
20 //实例化模型，调用模型方法
21 $result = FactoryModel::M('User')->checkLoginInfo($data);
22
23 //跳转提示
24 if($result){25 $this->msg('登录成功！', '?p=Admin&c=Index&a=index',3);26 } else {
27 $this->msg('用户名或密码不正确！！');
28 }
29 }
30 }Jump path modification after successful login operation
测试
1）模板准备：
准备后台视图模板程序。可以自己写前端视图模板程序，也可以到网上下载别人写好的前端模板，如到 模板之家 选择所需求的 前台，后台模板
寻找模板： www.mycodes.net
2） 将后台模板视图的静态资源文件（如 js, css,image）拷贝到 【Public/admin/】目录下
3） 创建后台首页控制器 【App/Controller/Admin/IndexController.class.php】
1 <?php
2 /**
3 * IndexController控制器类
4 * 后台相关操作
5 * User: young
6 */
7
8 class IndexController extends BaseController
9 {
10 //展示后台首页
11 public function index()
12 {
13 include 'App/View/Admin/Index/index.html';
14 }
15 }4) 创建后台首页视图 【App/View/Admin/Index/index.html】
1 <!doctype html>
2 <html>
3 <head>
4 <meta charset="UTF-8">
5 <title>后台管理</title>

效果及提交代码
代码提交，推送
1 $ git add -A 2 $ git commit -m "区分平台，实现后台首页" 3 $ git checkout master 4 $ git merge 'folder-model-app' 5 $ git push origin master
小结： 根据平台进一步优化目录结构，制作模型的单例工厂，实现后台首页
提出问题
1. 项目中可以看到 include或require的文件路径很长，容易出错，也不便于使用 ==> 如何更加简单引入且不易出错
2. 写一个类，就要到入口文件引入一次， 比较麻烦 ==> 如何实现自动加载类
3. 随着类的引入增加，入口文件代码量会越来越大 ==> 如何 封装，简化入口文件
4. 现在项目中任何一个目录，都可以随意访问 ==> 如何加强安全访问，限制目录的访问
下一步：常量使用，自动加载类实现，入口封装，限制目录访问

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.
Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
PHP: A Key Language for Web Development
Apr 13, 2025 am 12:08 AM
PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
How does PHP handle file uploads securely?
Apr 10, 2025 am 09:37 AM
PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.
How does PHP type hinting work, including scalar types, return types, union types, and nullable types?
Apr 17, 2025 am 12:25 AM
PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
The Enduring Relevance of PHP: Is It Still Alive?
Apr 14, 2025 am 12:12 AM
PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
PHP vs. Python: Understanding the Differences
Apr 11, 2025 am 12:15 AM
PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.
