MVC框架
先上图
客户端与控制器部分
控制器：controller.php
<?php//服务容器层namespace controller;use Closure;use config\model;use view\header;use view\index;use view\listinfo;use view\article;use view\footer;// require __DIR__ . '/atuoload.php';require __DIR__ . '/config/model.php';require __DIR__ . '/view/index.php';require __DIR__ . '/view/header.php';require __DIR__ . '/view/listinfo.php';require __DIR__ . '/view/article.php';require __DIR__ . '/view/footer.php';// 服务容器类class container{//容器属性时一个空数组，里面装创建对象的方法protected $instance = [];// 放进去，把实例化过程绑定到容器中// $alias 类实类的别名 可以自定义；Closure用于代表 匿名函数 的类public function bind($alias, Closure $process){//将类实例化的方法 存储到容器中$this->instance[$alias] = $process;}//取出来，执行容器中的实例方法public function make($alias, $arr = []){//call_user_func_array 回调函数，第一个是回调函数，第二个时索引数组//如call_user_func_array($a, $b) 把($a)作为回调函数调用，把参数数组作（$b）为回调函数的参数传入。return call_user_func_array($this->instance[$alias], $arr);}}$container = new container();$container->bind( 'model', function(){return new model();} );$container->bind('header', function(){return new header();});$container->bind('index', function(){return new index();});$container->bind('listinfo', function(){return new listinfo();});$container->bind('article', function(){return new article();});$container->bind('footer', function(){return new footer();});// facade门面类class Facade{private static $container = [];private static $data = [];// 导入容器，并静态化public static function initialize(container $container){static::$container = $container;}// 导出model，并静态化public static function model(){static::$data = static::$container->make('model')->getData();}// 导出视图index层，并静态化public static function index(){return static::$container->make('index')->index(static::$data);}// 导出视图header层，并静态化public static function header(){return static::$container->make('header')->head(static::$data);}// 导出视图list层，并静态化public static function listinfo(){return static::$container->make('listinfo')->listinfo(static::$data);}// 导出视图article层，并静态化public static function article(){return static::$container->make('article')->article(static::$data);}// 导出视图footer层，并静态化public static function footer(){return static::$container->make('footer')->footer();}}//控制器class demo{public function __construct(container $container){Facade::initialize($container);}public function index(){//导入数据Facade::model();//渲染首页模板Facade::header();Facade::index();Facade::footer();}public function list(){//导入数据Facade::model();//渲染列表页模板Facade::header();Facade::listinfo();Facade::footer();}public function article(){//导入数据Facade::model();//渲染内容页模板Facade::header();Facade::article();Facade::footer();}}$demo = new demo($container);
客户端首页：index.php
<?phprequire __DIR__ . '/controller.php';//客户端 首页echo $demo->index();
客户端列表页：list.php
注意：在模板中使用了 list.php?id= 请注意命名
<?phprequire __DIR__ . '/controller.php';//客户端 列表页echo $demo->list();
客户端 内容页：article.php
注意：在模板中使用了 article.php?id= 请注意命名
<?phprequire __DIR__ . '/controller.php';//客户端 内容页echo $demo->article();
数据库model.php
<?phpnamespace config;use PDO;class model{//pdoprivate static $pdo;//数据库表private static $table = null;public function __construct($dns='mysql:host=localhost;dbname=film',$user='root',$password='root'){static::$pdo = new PDO($dns,$user,$password);}//获取电影栏目表private static function listinfo($table='listinfo'){static::$table = $table;$sql = 'SELECT * FROM ' . static::$table;$stmt = static::$pdo->prepare($sql);$stmt->execute();return $stmt->fetchAll(PDO::FETCH_ASSOC);}//获取电影内容表private static function article($table='article'){static::$table = $table;$sql = 'SELECT * FROM ' . static::$table;$stmt = static::$pdo->prepare($sql);$stmt->execute();return $stmt->fetchAll(PDO::FETCH_ASSOC);}//获取会员表private static function user($table='user'){static::$table = $table;$sql = 'SELECT * FROM ' . static::$table . ' LIMIT 0,3';$stmt = static::$pdo->prepare($sql);$stmt->execute();return $stmt->fetchAll(PDO::FETCH_ASSOC);}//将电影栏目和内容详情页,会员数据包整合到一个类中public function getData(){return ['article'=>static::article(),'list'=>static::listinfo(),'user'=>static::user()];}}
1. 注意栏目主键与内容页索引关联
视图模板层
1.$vv[‘uid’] == $v[‘id’] 才能对应调用
index.php
<?phpnamespace view;class index{public function index($data){foreach ($data['list'] as $v){echo '<h2><a href="list.php?id=' . $v['id'] . '">' . $v['title'] . '</a></h2>';echo '<ul>';foreach($data['article'] as $vv){if($vv['uid'] == $v['id']){echo '<li><a href="article.php?id='. $vv['id'] .'">'.$vv['title'].'</a></li>';}}echo '</ul>';}}}?>
header.php
<?phpnamespace view;class header{public function head($data){echo '<header>';echo '<nav>';echo '<a href="/">首页</a>';foreach($data['list'] as $v){echo "<a href=list.php?id={$v['id']}>{$v['title']}</a>";}echo '</nav>';echo '</header>';}}echo '<style>a{text-decoration: none;color:#333;}header{width: 100%; height: 60px;background-color: lightcoral;}header>nav{height: 100%;display:grid;grid-template-columns: repeat(4,1fr);place-items: center;}header>nav>a{color:white;text-decoration: none;font-size: 20px;}footer{width: 100%; height: 60px;background-color: lightcoral;display: flex;justify-content: center;align-items: center;color: white;}</style>';?>
listinfo.php
通过$_GET对应调用
<?phpnamespace view;class listinfo{public function listinfo($data){foreach ($data['list'] as $v) {if($_GET['id'] == $v['id']){echo '<h2><a href="list.php?id=' . $_GET['id'] . '">' . $v['title'] . '</a></h2>';}}echo '<ul>';foreach ($data['article'] as $v) {if($_GET['id'] == $v['uid']){echo '<li><a href=article.php?id='.$v['id'].'>' . $v['title'] . '</a></li>';}}echo '</ul>';}}?>
article.php
<?phpnamespace view;class article{public function article($data){foreach ($data['article'] as $v) {if($_GET['id'] == $v['id']){echo '<h2>' . $v['title'] . '</h2>';echo '<img src=' . $v['img'] . '>';echo '<p>' . $v['newstext'] . '<p>';}}}}?>
footer.php
<?phpnamespace view;class footer{public function footer(){echo '<footer><p>php中文网</p></footer>';}}
总结：
1、完成了一个傻瓜式mvc，真的傻瓜式。
2、php相关知识串联学习，收获颇丰
3、来不及做会员登陆了，但已经有思路了
