Route::get('index','StudentController@getIndex');

class Student extends Model
{
  protected $table='student';       //指定数据库
  protected $fillable=['name','age','sex'];  //允许修改的字段
}

public static function getIndex(){
  return view('student.index',['students'=>Student::paginate(5)]);
}

@extends('student.layout')
@section('title')
  主页
  @stop
@section('content')
  !-- index页面自定义内容-->
  @stop
    在自定义内容里通过@foreach将学生数据信息循环显示到列表
@foreach($students as $student)
  tr>
    th scope="row">{{$student->id}}/th>
    td>{{$student->name}}/td>
    td>{{$student->age}}/td>
    td>{{$student->sex}}/td>
    td>{{$student->created_at}}/td>
  /tr>
@endforeach
