Create a Eloquent ORM Model for an existing database table

Code
<?php

use Illuminate\Database\Eloquent\Model;
use 
Illuminate\Database\ConnectionResolver;
use 
Illuminate\Database\Connection;
use 
Illuminate\Database\Query\Grammars\MySqlGrammar;

// Eloquent Model class for existing table "test"
class Test extends Model
{
    protected 
$table 'test';
    
    protected 
$connection 'default';
    
    public 
$timestamps false;
}

/* ### Configure Test model ### */

$pdo = new PDO('mysql:dbname=eloquent;host=127.0.0.1');

$connection = new Connection($pdo);
$connection->enableQueryLog();
$connection->setQueryGrammar(new MySqlGrammar());

$resolver = new ConnectionResolver([
    
'default' => $connection,
]);

Test::setConnectionResolver($resolver);

/* ### Work with Test model ### */

// Get all DB rows as Test instances and access columns
// with magic properties and ArrayAccess
$tests Test::all();
foreach (
$tests as $test) {
    echo 
$test->id ' - ' $test->name ' || ';
    echo 
$test['id'] . ' - ' $test['name'] . PHP_EOL;
}

// find one Test by id
$test Test::find(2);

// A few methods of Eloquent models
dump(
    
$test->getAttribute('id'),
    
$test->isDirty('name'),
    
$test->toJson(),
    
json_encode($test),
    
$test->toArray(), // Including relations, but Test has none
    
$test->attributesToArray() // Without relations
);

$test->setAttribute('name''newname');
dump(
    
$test->getAttribute('name'),
    
$test->isDirty('name')
);

echo 
$test;
Result
1 - foo || 1 - foo
2 - test || 2 - test
3 - bar || 3 - bar
