この記事はLaravelにてFakerを利用して、テストデータやSeederでダミーデータを作成する方法を解説します。

Fakerでダミーデータ作成

まずはFakerを利用してみるためにルーティングファイル（/routes/web.php）に以下のコードを記述しましょう。

既存のルーティングの「/」はコメントアウトするなりして無効または削除してください。

/routes/web.php

Route::get('/', function () {
    $faker = Faker\Factory::create('ja_JP');
    $dummyData = [
        'name' => $faker->name,
        'password' => $faker->password,
        'country' => $faker->country,
        'prefecture' => $faker->prefecture,
        'city' => $faker->city,
        'postcode' => $faker->postcode,
        'address' => $faker->address,
        'streetAddress' => $faker->streetAddress,
        'phoneNumber' => $faker->phoneNumber,
        'email' => $faker->email,
        'safeEmail' => $faker->safeEmail,
        'company' => $faker->company,
        'iso8601' => $faker->iso8601($max = 'now'),
        'dateTimeBetween' => $faker->dateTimeBetween($startDate = '-110 years', $endDate = 'now')->format('Y年m月d日'),
        'numberBetween' => $faker->numberBetween($min = 100, $max = 200),
        'title' => $faker->title,
        'realText' => $faker->realText($maxNbChars = 50, $indexSize = 2),
        'randomNumber' => $faker->randomNumber($nbDigits = 5),
        'randomFloat' => $faker->randomFloat($nbMaxDecimals = 4, $min = 0, $max = 5),
        'randomElement' => $faker->randomElement($array = ['男性', '女性']),
        'lexify' => $faker->lexify($string = '??????'),
        'hexcolor' => $faker->hexcolor,
        'ipv4' => $faker->ipv4,
        'url' => $faker->url,
        'imageUrl' => $faker->imageUrl($width = 640, $height = 480, $category = 'cats', $randomize = true, $word = null),
        'userAgent' => $faker->userAgent,
        'creditCardType' => $faker->creditCardType,
        'creditCardNumber' => $faker->creditCardNumber,
        'creditCardExpirationDate' => $faker->creditCardExpirationDate,
        'isbn13' => $faker->isbn13,
        'isbn10' => $faker->isbn10
    ];
    dd($dummyData);
    exit();
});

PHP

http://localhost/にアクセスして結果を見てみると以下のような結果となると思います。
（実行するたびに結果が異なるため、完全に同一とはなりません。）
