说到‘faker’，是不是会联想到那个叱咤LOL界的大魔王？哈哈，此‘faker’非彼‘faker’,但是，这个faker也可以号称一个大魔王，测试数据生成的大魔王。

学习laravel时，学习到一种快速的数据填充的方式，简洁好用，轻松解决测试数据填充的麻烦，废话不多说，下面开始介绍faker。

官方地址：https://github.com/fzaninotto/Faker

使用方式：

1、composer直接下载： composer require fzaninotto/faker

2、将 "fzaninotto/faker": "^1.8" 加入composer.json，执行composer update

3、github下载到本地

引入项目和简单使用：

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

$faker = Faker\Factory::create('zh_CN'); //选择中文

//var_dump($faker);

//简单使用，可用循环输出多个。

echo $faker->name(),' '; //陶洋

echo $faker->address(),' '; //成都沈河区

echo $faker->email(),' '; //voluptate60@sina.com

echo '<hr>';

中文简体所有可以使用的方法：

//所有方法：语言包不同，返回结果会有差异。

Ex autem dolor nesciunt.', 2 => 'Recusandae minima doloremque sit facilis minus est deserunt. Sed sint velit eos tempora ad. Non laborum laboriosam qui asperiores et. Eum impedit ea qui corporis alias non.', )

示例：

ps：此示例在tp5.1下，配合seed使用。

<?php

use think\migration\Seeder;

use Faker\Factory;

class ItemSeeder extends Seeder

{

/**

* Run Method.

* Write your database seeder using this method.

* More information on writing seeders is available here:

* http://docs.phinx.org/en/latest/seeding.html

public function run()

{

$faker = Factory::create('zh_CN');

$data = [];

//创建数据

for ($i = 0; $i < 3; $i++){

$data[$i]['title'] = $faker->name();

$data[$i]['version'] = '1.0';

$data[$i]['status'] = $faker->numberBetween(0,1);

$data[$i]['user_id'] = 1;

$data[$i]['description'] = $faker->realText(10, 2);

$data[$i]['coll_num'] = 0;

$data[$i]['create_time'] = $faker->date('Y-m-d H:i:s','now');

$data[$i]['update_time'] = $faker->date('Y-m-d H:i:s','now');

$data[$i]['appid'] = $faker->md5();

$data[$i]['appsecret'] = $faker->md5();

$data[$i]['code'] = $faker->md5();

}

$table = $this->table('hbb_item');

$table->insert($data)->save();

}

在跟目录下运行php think seed:run
