EloquentをLaravelなしに使う

7
Posted at

LaravelのORMのEloquentを単体で使う方法を解説する。

illuminate/databaseをインストールする:

composer require illuminate/database

Eloquent単体での使い方:

<?php

declare(strict_types=1);

require __DIR__ . '/vendor/autoload.php';

use Illuminate\Database\Capsule\Manager as DB;
use Illuminate\Database\Schema\Blueprint;

$db = new DB();

$connectionName = 'default';

// DBの接続設定
$db->addConnection(
    [
        'driver' => 'mysql',
        'host' => '127.0.0.1',
        'database' => 'development',
        'username' => 'root',
        'password' => 'root',
        'charset' => 'utf8mb4',
        'collation' => 'utf8mb4_ja_0900_as_cs_ks',
    ],
    $connectionName
);

// DBへのコネクションを取得する
$connection = $db->getConnection($connectionName);

// テーブルがなければ作る
$connection->getSchemaBuilder()->hasTable('user')
|| $connection->getSchemaBuilder()->create(
    'user',
    function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->string('email');
        $table->timestamps();
    }
);

// テーブルを空っぽにする
$connection->table('user')->truncate();

$now = new DateTimeImmutable();

// 1レコードinsertする
$connection->table('user')->insert(
    [
        'name' => 'alice',
        'email' => 'alice@example.com',
        'created_at' => $now,
        'updated_at' => $now,
    ]
);

// insertしたレコードを取得する
$alice = $connection->table('user')->find(1);

// 期待したとおりのレコードが取れているか?
assert(
    $alice == (object) [
        'id' => 1,
        'name' => 'alice',
        'email' => 'alice@example.com',
        'created_at' => $now->format('Y-m-d H:i:s'),
        'updated_at' => $now->format('Y-m-d H:i:s'),
    ]
);
