laravel控制器与路由的简单应用

1、laravel控制器

代码示例——后端

<?php
namespace App\Http\Controllers\admin;
use App\Http\Controllers\controller;
use Illuminate\Support\Facades\DB;
class Index extends Controller{
    public function  index(){
        return view("index");
    }
    //获取数据
    public function get(){
       $res = DB::select('select * from users ');
       $lists = [];
       foreach($res as $val){          
          $lists[] = (array)$val;          
       } 
       $data['result'] = $lists;
       return view("index",$data);
    }
    //插入用户数据
    public function insert(){
        $data = time();
        $res = DB::insert('insert users(`name`,`pwd`,`email`,`add_time`)values("ccc","123456","asd@qq.com","$data")');
        print_r($res);
    }
    //更新数据
    public function update(){
        $data = time();
        $res = DB::update("update users set add_time = $data where id=5");
        var_dump($res);
    }
    //删除数据
    public function delete(){
        $res = DB::delete("delete from users where id=5");
        var_dump($res);
    }
}

代码示例——前端

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" type="text/css" href="/layui/css/layui.css">
    <title>首页</title>
</head>
<body>
<div style="margin:auto;width:500px">
        <table class="layui-table">
            <caption align="top">用户信息</caption>
            <thead>
            <tr>
                <th>ID</th>
                <th>用户名</th>
                <th>email</th>
                <th>添加时间</th>
            </tr>
            </thead>
            <tbody>
            <?php foreach($result as $val)  { ?>
                <tr>
                    <th><?php echo $val['id'] ?></th>
                    <th><?php echo $val['name'] ?></th>
                    <th><?php echo $val['email'] ?></th>
                    <th><?php echo  date("y-m-d   H:i:s", $val['add_time']); ?></th>
                </tr>
            <?php } ?>
            </tbody>
        </table>
</div>
</body>
</html>

2、路由

代码示例

<?php
use Illuminate\Support\Facades\Route;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/', function () {
    return view('welcome');
});
Route::get('/admin/index','admin\Index@index');
Route::get('/admin/index/get','admin\Index@get');
Route::get('/admin/index/insert','admin\Index@insert');
Route::get('/admin/index/update','admin\Index@update');
Route::get('/admin/index/delete','admin\Index@delete');
