PHP Faker 使用手册
PHP Faker 是一款用于生成各种随机串的工具库，通常用于在项目测试时生成大量样本数据。注：本文仅对官方文档进行摘抄并添加了少量的测试代码，毕竟这并不是什么高深的技巧。

composer require fzaninotto/faker
Basic Usage
使用前先执行 $faker = Faker\Factory::create();
// generate data by accessing properties
echo $faker->name;
// 'Lucy Cechtelar';
echo $faker->address;
// "426 Jordy Lodge
// Cartwrightshire, SC 88120-6700"
echo $faker->text;
// Dolores sit sint laboriosam dolorem culpa et autem. Beatae nam sunt fugit
// et sit et mollitia sed.
// Fuga deserunt tempora facere magni omnis. Omnis quia temporibus laudantium
// sit minima sint.

Modifiers 修改器，即执行生成方法前可以调整生成系数
// unique() forces providers to return unique values

// tip: unique() keeps one array of values per provider
// optional() sometimes bypasses the provider to return a default value instead (which defaults to NULL)

// get a random digit, but also null sometimes

自定义Provider
- 创建一个自定义的Provider
namespace Faker\Provider;
class Book extends \Faker\Provider\Base
{
public function title($nbWords = 5)
{
$sentence = $this->generator->sentence($nbWords);
return substr($sentence, 0, strlen($sentence) - 1);
}
public function ISBN()
{
return $this->generator->ean13();
}
}
- 调用前引入Provider
$faker->addProvider(new \Faker\Provider\Book($faker));
- 愉快的使用
$book = new Book();
$book->setTitle($faker->title);
$book->setISBN($faker->ISBN);
$book->setSummary($faker->text);
$book->setPrice($faker->randomNumber(2));
调用时使用方法也是可以的，如：
$book->setTitle($faker->title());
Localization
$faker = Faker\Factory::create('fr_FR'); // create a French faker
for ($i=0; $i < 10; $i++) {
echo $faker->name, "\n";
}
// Luce du Coulon
// Auguste Dupont
// Roger Le Voisin
// Alexandre Lacroix
// Jacques Humbert-Roy
// Thérèse Guillet-Andre
// Gilles Gros-Bodin
// Amélie Pires
// Marcel Laporte
// Geneviève Marchal
Provider 本地化配置
注意：本地化并不意味着全部随机项都有相应的配置，如：银行账号。如果有必要的话可以考虑继承一个
\Faker\Provider\*自己实现。有些接口必须添加Provider才能用，并且locale不同名字也会有差异。
