Faker 是一個用來生成數(shù)據(jù)庫實例數(shù)據(jù)的工具。Faker is a PHP library that generates fake data for you. Whether you need to bootstrap your database, create good-looking XML documents, fill-in your persistence to stress test it, or anonymize data taken from a production service, Faker is for you.

installation

composer require fzaninotto/faker

basic usage

Use Faker\Factory::create() to create and initialize a faker generator, which can generate data by accessing properties named after the type of data you want.

<?php

require_once '/path/to/Faker/src/autoload.php';
$faker = Faker\Factory::create();
echo $faker->name;
echo $faker->address;
echo $faker->text;
echo $faker->email;

在src/Faker/Generator.php 中狠多種類型可以參考，包括file，image，uuid 各種數(shù)據(jù)類型。

在laravel 中的使用

Laravel artisan 的 tinker 是一個 REPL (read-eval-print-loop) ，REPL 是指 交互式命令行界面，它可以讓你輸入一段代碼去執(zhí)行，并把執(zhí)行結果直接打印到命令行界面里。通過php artisan tinker 和faker結合之后，可以直接用來測試。Tinker 是 Laravel 自帶的 REPL，基于 PsySH 構建而來。同樣需要psysh的支持。

使用示例如下：

php artisan tinker
//這是是使用faker的工廠模式生成數(shù)據(jù)，其中App\User需要在database\factories\ModelFactories 文件中提前寫好需要設置的數(shù)據(jù)類型和字段
factory("App\User::class",10)->create(); 
//查詢
APP\User::all(); 
App\User::count();
//增加數(shù)據(jù)
$user = new App\User;
$user->name = "Wruce Bayne";
$user->email = "iambatman@savegotham.com";
$user->save();
// 刪除數(shù)據(jù)
$user = App\User::find(1);
$user->delete();

// 還可以查看doc幫助
doc dd
doc app
  
// 顯示源代碼
 show <functionName>
