composerを用いてライブラリ（Faker）を使ってみた

今回はcomposerを使って便利なライブラリ「Faker」を使ってみたいと思います。

#前提条件
composerのインストールまでは完了している事とします。

composerバージョンチェック
composer --version

Composer version 2.0.8 2020-12-03 17:20:38

任意のディレクトリに移動
cd <任意のディレクトリ>

composer.jsonを作成する
composer require fakerphp/faker

composer.jsonの中はこんな感じになっています。

composer.json

{
    "require": {
        "fakerphp/faker": "^1.15"
    }
}

検証用プログラム

faker.php

<?php

    require_once '../vendor/autoload.php';

    $faker = Faker\Factory::create('ja_JP');

    $gender = ['男性','女性', 'その他'];
    $createCnt = 2;

    $result = array();
    for($i=0; $i<$createCnt; $i++)
    {
        $result[$i]["name"]           = $faker->name;
        $result[$i]["homePostcode"]   = "〒". preg_replace("/^.{0,3}+\K/us", '-', $faker->postcode);
        $result[$i]["homeAddress"]    = $faker->prefecture. " ". $faker->city. " ". $faker->streetAddress;
        $result[$i]["userName"]       = $faker->userName;
        $result[$i]["password"]       = $faker->password;
        $result[$i]["email"]          = $faker->email;
        $result[$i]["phoneNumber"]    = $faker->phoneNumber;
        $result[$i]["birthDay"]       = $faker->date($format='Y-m-d',$max='now');
        $result[$i]["companyName"]    = $faker->company;
        $result[$i]["companyPostcode"]   = "〒". preg_replace("/^.{0,3}+\K/us", '-', $faker->postcode);
        $result[$i]["companyNumber"]     = $faker->phoneNumber;
        $result[$i]["creditCardNumber"]  = $faker->creditCardNumber;
        $result[$i]["randomElement"]     = $faker->randomElement($gender);        
    }

    echo '<pre>';
    var_dump($result);

データの精度は高くないものの、
すぐにダミーデータが必要な場合は重宝しそうですね。
