【thinkphp5框架的目录结构，以及使用框架model 、controler、view的使用，以及错误调试和日志记录】

ThinkPHP5 在php5.5版本以上”No input file specified“问题解决：

　　public/.htaccess文件中的

　　RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]

　　在默认情况下会导致No input file specified.

　　修改成

　　RewriteRule ^(.*)$ index.php [L,E=PATH_INFO:$1]

　　问题解决

配置文件的使用

application/index.controller/Demo.php

<?php
namespace app\index\controller;
use think\Config;

class Demo extends Base{
    // 配置文件的使用
    public function config() {
        // 默认一页显示15条
        $config = Config::get("paginate");
        dump($config);//15

        $config = config("paginate.type");
        dump(config("?paginate"));//boolean true

        $config = config("paginate.type");
        dump(config("?paginate111"));//boolean false

        dump(Config::has("paginate"));//boolean true

        dump(config("cyy"));
        // array (size=1)
          // cyy' => int 1
  
        dump(config("redis.host"));//string '127.0.0.1'
    }
}

application/extra/redis.php

<?php
// 配置文件的使用
return [
    "host" => "127.0.0.1",
];

application/index/config/php

<?php

// 配置文件的使用
return [
    "cyy" => [
        'cyy' => 1,
        
    ]
];

路由的使用

自定义路由

application/index/controller/Video.php

<?php
namespace app\index\controller;

class Video extends Controller {

    // 自定义路由
    public function getVideo() {
        $id = input("param.id");

        // http://phptest.com/index/video/getVideo?id=2
        //  => 域名/video/2
        dump($id);
    }
}

application/route.php

use think\Route;

// 自定义路由 域名/video/2
// Route::rule("video/:id", "index/Video/getVideo");
//Route::get("video/:id", "index/Video/getVideo");// 定义Get请求路由
//Route::post("video/:id", "index/Video/getVideo");// 定义Post请求路由

// 组合写法
Route::get([
    'video/:id' => ["index/Video/getVideo", [], ['id' => '\d+']],
]);

控制器的使用

application/index/controller/Demo.php

<?php
namespace app\index\controller;
use think\Config;
use think\Request;

class Demo extends Base{
    /**
     * 初始化
     * @auth   cyy
     * @return [type] [description]
     */
    public function _initialize() {
        dump("这是initialize");
    }
    public function test() {
        // 数组转json格式返回
        return json(["as" => 1, "cyy" => "test"]);
    }

    public function hello() {
        var_dump(input("param."));
        return "index-index-hello";
    }

    // 控制器-跳转
    public function abc() {
        $id = input("param.id", 0, "intval");
        if($id == 1) {
            $this->success("操作成功", "admin/index/index");
        }elseif($id == 2) {
            $this->error("操作失败");
        }    

    }

    // 控制器-重定向
    public function ef() {
        $this->redirect("hello", ["id" => 1, "ms" => 123]);
        //redirect("https://baidu.com");
    }

    // 控制器-请求
    public function requestData() {
        $request =  Request::instance();
        //访问http://phptest.com/index/demo/requestData?ids=2
        dump(request()->isPost());//boolean false
        dump(input("?get.ids"));//boolean true
        dump(request()->has("ids", "get"));//boolean true
    }
}

application/index/controller/Base.php

<?php
namespace app\index\controller;
use think\Controller;
class Base extends Controller {

    /**
     * 空操作
     * @auth   singwa
     * @param  [type] $name [description]
     * @return [type]       [description]
     */
    // 控制器-空操作
    public function _empty($name) {
        // todo
        return $name;
    }
}

数据库配置与model层数据操作

    // 数据库调试模式
