1. Table structure

I am using users table in the example.

CREATE TABLE `users` (
  `id` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
  `username` varchar(80) NOT NULL,
  `name` varchar(80) NOT NULL,
  `email` varchar(80) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

2. Database Configuration

Open .env file.

Specify the host, database name, username, and password.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=tutorial
DB_USERNAME=root
DB_PASSWORD=

3. Model

Create Model –

  • Open Command Prompt.
  • Navigate to your project directory.
  • Execute php artisan make:model Page. Here, I created Page model.
  • This will create a new file Page.php in app/ directory.

Load DB Class and create method –

  • Navigate to app/ directory and open Page.php.
  • Import DB class use DB;.
  • Create single static method getuserData().
  • Fetch all records from the users table using DB::table('users')->orderBy('id','asc')->get().
  • Return $value.

NOTE – To use DB for database manipulation need to import DB class with use DB;.

Completed Code

<?php

namespace App;
use DB;
use Illuminate\Database\Eloquent\Model;

class Page extends Model {
  public static function getuserData(){
    $value=DB::table('users')->orderBy('id', 'asc')->get();
    return $value;
  }
}

  • Navigate to app/Http/Controllers/ directory and open PagesController.php.
  • Import Page Model from App namespace with use App\Page outside of class.
  • Create an index() method where call getuserData() method of Page model Page::getuserData() to fetch users data.
  • Store in $userData variable and pass to index view.

Completed Code

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Page;

class PagesController extends Controller{
 
  public function index(){
 
    // Read value from Model method
    $userData = Page::getuserData();

    // Pass to view
    return view('index')->with("userData",$userData);
  }

}

5. Route

Open web.php file in route/ directory.

Defined single route.

Completed Code

<?php

// Controller-name@method-name
Route::get('/', 'PagesController@index'); // localhost:8000/

Create a new file index.blade.php in resources/views/ directory.

Read values from $userData using @foreach and create new rows.

Completed Code

<!doctype html>
<html>
  <body>
    <table border='1' style='border-collapse: collapse;'>
      <tr>
        <th>Username</th>
        <th>Name</th>
        <th>Email</th>
      </tr>
      @foreach($userData as $user)
      <tr>
        <td>{{ $user->username }}</td>
        <td>{{ $user->name }}</td>
        <td>{{ $user->email }}</td>
      </tr>
