Use Eloquent ORM in PHP projects without Laravel

dev_lak

When talking about Laravel Framework, Eloquent is a one of best part of the framework, have you ever thought of using Eloquent without entire Laravel framework? In this post i'm teaching you how to use Eloquent ORM without Laravel Framework, i'll create simple form using Eloquent. Let's dive,

Required Environment

Windows/Mac or Linux
Apache server
PHP 7+

Setting up Eloquent in PHP

First move to empty folder on public directory and run below command on terminal.

composer require illuminate/database

This will generate composer.json and install eloquent dependency on our project directory.

After command successful, create a new file and name it bootstrap.php and put below code in it,

<?php

require "vendor/autoload.php";

use Illuminate\Database\Capsule\Manager as Capsule;

$capsule = new Capsule;

// Mysql serve credentials
$capsule->addConnection([
   "driver" => "mysql",
   "host" =>"127.0.0.1",
   "database" => "ums",
   "username" => "root",
   "password" => "123"
]);

// Making Capsule instance available globally
$capsule->setAsGlobal();

// Booting the Eloquent ORM
$capsule->bootEloquent();

The code requiring composer autoload class and importing Eloquent Manager and making it's instance called $capsule. In next line we setting database connection and making it available globally using $capsule instance, finally we're booting the Eloquent ORM.

After this create a database on your localhost and name it ums

Creating Migrations

Migration is used to build your application database schema, in Laravel we use artisan commands to generate migrations and run them, so let's see how we can use migrations without Laravel Framework and artisan commands.

Now create a folder called database and create user_table_migration.php inside the newly created folder and put below code

<?php

require "../bootstrap.php";

use Illuminate\Database\Capsule\Manager as Capsule;

Capsule::schema()->create('users', function ($table) {
    $table->increments('id');
    $table->string('name');
    $table->string('email')->unique();
    $table->string('password');
    $table->timestamps();
});

You can see a some similarity of this code and what we would write in Laravel, the difference is the schema is reference from Capsule class.

Now our migration for users table is ready, to run this migration simply open user_table_migration.php file on browser if you see a blank page, it means script executed successfully, to verify check your database, there should be users table created.

Note - Since these migration scripts publicly available, this is not suitable for Production use

Creating Models

Let's see how we implement Eloquent Models, first create a new folder and name it models, then open composer.json and edit it like below code

{
    "require": {
        "illuminate/database": "^7.5"
    },
    "autoload": {
        "classmap": [
            "models"
        ]
    }
}

This will add our models folder as autoload, now create a new file inside models folder and name it User.php

<?php

use Illuminate\Database\Eloquent\Model as Eloquent;

class User extends Eloquent
{
   /**
   * The attributes that are mass assignable.
   *
   * @var array
   */
   protected $fillable = [
       'name', 'email', 'password'
   ];

   /**
   * The attributes that should be hidden for arrays.
   *
   * @var array
   */
   protected $hidden = [
       'password',
   ];
 }

Now our Eloquent Models are ready to use, let's create form to insert data.

Create a new file in the root of the project and name it index.php, then put below code

<?php
    session_start();

    $error = isset($_SESSION['error']) ? $_SESSION['error']:true;
?>

                                    <?php
                                        if ($error == false) {
                                            echo '<span>User added</span>';
                                        }
                                    ?>
                                </form>
                            </div>
                        </div>
                    </div>
                </div>
            </div>
        </section>
        
        <script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="sha384-J6qa4849blE2+poT4WnyKhv5vZF5SrPo0iEjwBvKU7imGFAV0wwj1yYfoRSJoZ+n" crossorigin="anonymous"></script>

    </body>
</html>

Here i'm using bootstrap for frontend, now our form is ready. Then we need another php script to handle form submit so create another file and name it save_user.php and put below code,

<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

session_start();

require "bootstrap.php";

$name = $_POST['name'];
$email = $_POST['email'];
$password = password_hash($_POST['password'], PASSWORD_BCRYPT);

$user = User::create([
    'name' => $name,
    'email' => $email,
    'password' => $password,
]);

$_SESSION['error'] = false;

header('Location: index.php');

This will handle our form submit event and insert the data to database using Eloquent. Finally open your terminal and run below command,

composer dump-autoload -o

This will generate optimised autoload files for our project. Now open index.php from browser and enter some info into form and see what happened.
