项目提交composer的packagist
项目提交至github
github注册账号
创建一个项目
, (*1)
安装composer, (*2)
composer init
初始化项目composer init初始化之后会自动声场vendor目录以及composer.json文件
|--app(开发者写代码的地方) | |--home(前台模块) | | |--controller(控制器类) | | |--view(视图) |--houdunwang(系统核心) | |--core | |--model | |--view |--public(入口、静态资源) | |--static(静态资源) | |--view(公共模板文件) |--system(配置) | |--config (配置项) | |--model (处理业务的各种模型类)
MVC M---model V--view C--controller###3.创建框架的启动类houdunwang\core\Boot.php类`类名和文件名首字母大写`<?php //命名空间 namespace houdunwang\core; class Boot { public static function run () { echo 'run'; } }
<?php namespace houdunwang\core; class Boot { public static function run () { //错误处理 self::handler(); //初始化框架 self::init(); //执行应用 self::appRun (); } public static function handler(){ $whoops = new \Whoops\Run; $whoops->pushHandler(new \Whoops\Handler\PrettyPageHandler); $whoops->register(); } public static function init() { session_id () || session_start (); date_default_timezone_set ('PRC'); } public static function appRun () { if ( isset( $_GET[ 's' ] ) ) { $info = explode ('/',$_GET['s']); $info[1] = ucfirst ($info[1]); $class = "\app\\{$info[0]}\controller\\{$info[1]}"; $action = $info[2]; define ('MODULE',strtolower ($info[0])); define ('CONTROLLER',lcfirst ($info[1])); define ('ACTION',$info[2]); } else { $class = "\app\home\controller\Entry"; $action = "index"; define ('MODULE','home'); define ('CONTROLLER','entry'); define ('ACTION',$action); } echo call_user_func_array ( [ new $class , $action ] , [] ); exit; } }
<?php require_once '../vendor/autoload.php'; \houdunwang\core\Boot::run ();
这个时候报错:, (*3)
Fatal error: Class 'houdunwang\core\Boot' not found in /Applications/MAMP/htdocs/frame/public/index.php on line 3
因为类加载使用时需满足:include加载文件和导入命名空间
继续往下解决这个问题, (*4)
修改composer.json文件。注意autoload
该项需自己增加, (*5)
{ "name": "chaorenwubin/frame", "description": "后盾网php框架系统", "type": "project", "licence":"MIT", "authors": [ { "name": "武斌", "email": "wubin.mail@foxmail.com" } ], "minimum-stability": "dev", "require": {}, "autoload":{ "files":[], "psr-4":{ "houdunwang\\":"houdunwang\\", "app\\":"app\\" } } }
PSR-4, (*6)
1.是制定的代码规范,简称PSR,是代码开发的事实标准 2.PSR-4使代码更加规范,能够满足面向package的自动加载,它规范了如何从文件路径自动加载类,同时规范了自动加载文件的位置 3.如果是: "houdunwang\\":"houdunwang\\",当实例化\houdunwang\core\Boot类时,会加载houdunwang/core/Boot.php 4.如果是: "houdunwang\\":"hdphp\\",当实例化\houdunwang\core\Boot类时,hdphp/core/Boot.php 5.如果是: "houdunwang\\":"",当实例化\houdunwang\core\Boot类时,Boot.php 5.反斜线是转义
生成composer自动载入文件,在Terminal中进入项目跟目录执行:, (*7)
composer dump
这时,访问项目入口public文件输出run
, (*8)
引入助手函数, (*9)
1.将以前我们写的helper.php文件放入system/helper.php 2.修改composer.json文件中autoload项的files "autoload":{ "files":[ "system/helper.php" ], "psr-4":{ "houdunwang\\":"houdunwang\\", "app\\":"app\\" } } 3.在Teminal终端执行composer dump
appRun方法具体代码, (*10)
public static function appRun () { if(isset($_GET['s'])){ //通过?s=模块/控制器/方法(?s=home/entry/index)进行访问 //接受get参数s,并将其转为数组 $info = explode ('/',$_GET['s']); //dd($info); $info[1] = ucfirst ($info[1]); //dd($info); $c = "app\\{$info[0]}\controller\\{$info[1]}"; $a = $info[2]; define ('MODULE',strtolower ($info[0])); define ('CONTROLLER',strtolower ($c)); define ('ACTION',$a); }else{ $c = "\app\home\controller\\entry";//控制器类 $a = 'index';//方法 define ('MODULE','home'); define ('CONTROLLER','entry'); define ('ACTION',$a); } return call_user_func_array ([new $c,$a],[]); }
在app/home/controller中创建Entry.php, (*11)
<?php namespace app\home\controller; class Entry { public function index(){ echo 'Welcome'; } }
通过地址栏访问public
或public/index.php
或public/index.php?s=home/entry/index
也可通过尝试其他地址访问,如:public/index.php?s=home/entry/store
浏览器正常输出Welcome
, (*12)
public/view放入message.php模板文件
, (*13)
自己参考代码
在 core 目录中创建Controller.php,并让app\home\controller\Entry.php及以后类继承Controller, (*14)
<?php namespace houdunwang\core; class Controller { private $url; protected function message($msg){ include './view/message.php'; exit; } protected function setRedirect($url = ''){ if($url){ $this->url = "location.href='$url'"; }else{ $this->url = "window.history.back()"; } return $this } }
app/controller/Entry.php,中增加store方法进行测试,增加store方法进行测试
通过地址栏访问store方法:public/index.php?s=home/entry/store
可看到提示页面,3秒之后自动跳转, (*15)
<?php namespace app\home\controller; use houdunwang\core\Controller; class Entry extends Controller { public function index(){ echo 'Welcome'; } public function store(){ $this->setRedirect ('?s=home/entry/index')->message ('添加成功'); } }
在core/view目录中建立View.php和Base.php
View.php, (*16)
<?php namespace houdunwang\view; class View { public function __call ( $name , $arguments ) { // TODO: Implement __call() method. return self::parseAction ( $name , $arguments ); } public static function __callStatic ( $name , $arguments ) { // TODO: Implement __callStatic() method. return self::parseAction ( $name , $arguments ); } public static function parseAction ( $name , $arguments ) { return call_user_func_array ( [ new Base , $name ] , $arguments ); } }
Base.php, (*17)
<?php namespace houdunwang\view; class Base { private $file; private $data; public function make () { $this->file = "../app/" . MODULE . '/view/' . CONTROLLER . '/' . ACTION . '.php'; return $this; } public function with ( $var ) { $this->data = $var; return $this; } //当输出对象的时候出发,比如说echo $obj->make(); public function __toString () { // TODO: Implement __toString() method. extract ($this->data); include $this->file; return ''; } }
数据库配置项文件system/config/database.php
, (*18)
<?php return [ 'driver'=>'mysql', 'host' => '127.0.0.1', 'user' => 'root', 'password' => 'root', 'dbname' => '', ];
system/helper.php助手函数中增加加载配置项的c函数, (*19)
function c ( $path ) { $info = explode ( '.' , $path ); $config = include "../system/config/" . $info[ 0 ] . '.php'; return isset( $config[ $info[ 1 ] ] ) ? $config[ $info[ 1 ] ] : null; }
houdunwang/model/Model.php
, (*20)
<?php namespace houdunwang\model; class Model { /** * @param $name * @param $arguments */ public function __call ( $name , $arguments ) { // TODO: Implement __call() method. return self::parseAction ( $name , $arguments ); } /** * @param $name * @param $arguments */ public static function __callStatic ( $name , $arguments ) { // TODO: Implement __callStatic() method. return self::parseAction ( $name , $arguments ); } /** * @param $name * @param $arguments * * @return mixed */ public static function parseAction ( $name , $arguments ) { $class = get_called_class (); return call_user_func_array ( [ new Base($class) , $name ] , $arguments ); } }
base.php, (*21)
<?php namespace houdunwang\model; use PDO; use PDOException; use Exception; /** * 模型基础类 * Class Base * * @package houdunwang\model */ class Base { protected $pdo; public function __construct ( $class ) { //1.链接数据库 $this->connect (); //$class打印结果:system\model\Article $class = explode ( '\\' , $class ); $this->table = strtolower ( $class[ 2 ] ); } private function connect () { $dsn = c ( 'database.driver' ) . ":host=" . c ( 'database.host' ) . ";dbname=" . c ( 'database.dbname' ); $user = c ( 'database.user' ); $password = c ( 'database.password' ); try { $this->pdo = new PDO( $dsn , $user , $password );//链接数据库 $this->pdo->query ( 'SET NAMES UTF8' );//设置字符集 //设置错误属性 $this->pdo->setAttribute ( PDO::ATTR_ERRMODE , PDO::ERRMODE_EXCEPTION ); } catch ( PDOException $e ) { //输出错误 exit( $e->getMessage () ); } } /** * 执行有结果集的查询 * * @param $sql 查询的sql语句 * * @return mixed 查询结果结 */ public function query ( $sql ) { try { $res = $this->pdo->query ( $sql ); return $res->fetchAll ( PDO::FETCH_ASSOC ); } catch ( PDOException $e ) { throw new Exception( "sql:{$sql} | " . $e->getMessage () ); } } public function exec ( $sql ) { try { $affectedRows = $this->pdo->exec ( $sql ); if ( $lastInsertId = $this->pdo->lastInsertId () ) { //返回自增id return $lastInsertId; } else {//否则返回受影响的条数 return $affectedRows; } } catch ( PDOException $e ) { throw new Exception( "sql:{$sql} | " . $e->getMessage () ); } } }
需要在system/model建立Article.php进行协助测试测试,Article.php名字不是固定的, (*22)
<?php namespace system\model; use houdunwang\model\Model; class Article extends Model { }
在Entry.php中进行测试,注意system中的类不会自动进行加载,需要修改composer.json配置项, (*23)
"autoload":{ "files":[ "system/helper.php" ], "psr-4":{ "houdunwang\\":"houdunwang", "app\\":"app\\", "system\\":"system\\" } }
然后执行, (*24)
composer dump
composer的packagist(https://packagist.org/)搜索:whoop
选择第一个:filp/whoops
进入到项目根目录执行:, (*25)
composer require filp/whoops
在houdunwang/core/Boot.php中加入, (*26)
$whoops = new \Whoops\Run; $whoops->pushHandler(new \Whoops\Handler\PrettyPageHandler); $whoops->register();
推送上到composer仓库之后即可以下载了, (*27)
