day5の今日は、1件のレコードを削除する(SQL的にはDELETE)やり方を見ていきます。

Doctrine

<?php

declare(strict_types=1);

use App\Entity\Book;
use Doctrine\ORM\EntityManagerInterface;

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

/** @var EntityManagerInterface $entityManager */
$entityManager = require __DIR__.'/bootstrap.php';

$book1 = $entityManager->getRepository(Book::class)->find(1);

$entityManager->remove($book1);
$entityManager->flush();

  • day3の方法でBookエンティティのインスタンスを取得します。
  • EntityManagerの remove() メソッドにBookエンティティを渡し、その後にEntityManagerの flush() メソッドを呼びます。
  • DELETE文はremove()を呼び出したときでなくflush()を呼び出したときに実行されます。

Eloquent

<?php

declare(strict_types=1);

use App\Models\Book;

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

$book1 = Book::find(1);
$book1->delete();

https://github.com/77web/doctrine-vs-eloquent/blob/c0e4819f8f10c36d7ae553203ca6fdec05755a0d/Eloquent/Usecase/delete_one_record.php

  • day3 の方法でBookモデルのインスタンスを取得します。
  • Bookモデルのインスタンスの delete() メソッドを呼び出します。
