• Allo点评：Faker是一个很神奇的项目，会自动生成拟真的数据，包括用户资料、长文本、IP、日期等等，在网站上线前测试时非常好用。

基本使用：

Use FakerFactory::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 the Faker autoloader
require_once '/path/to/Faker/src/autoload.php';
// alternatively, use another PSR-0 compliant autoloader (like the Symfony2 ClassLoader for instance)

// use the factory to create a FakerGenerator instance
$faker = FakerFactory::create();

// generate data by accessing properties
echo $faker->name;
  // 'Lucy Cechtelar';
echo $faker->address;
  // "426 Jordy Lodge
  // Cartwrightshire, SC 88120-6700"
echo $faker->text;

Even if this example shows a property access, each call to $faker->name yields a different (random) result. This is because Faker uses __get() magic, and forwards FakerGenerator->$property calls toFakerGenerator->format($property).

<?php
for ($i=0; $i < 10; $i++) {
  echo $faker->name, "
";
}

Formatters

Each of the generator properties (like name, address, and lorem) are called "formatters". A faker generator has many of them, packaged in "providers". Here is a list of the bundled formatters in the default locale.

FakerProviderBase

randomDigit             // 7
randomDigitNotNull      // 5
randomNumber($nbDigits = NULL) // 79907610
randomFloat($nbMaxDecimals = NULL, $min = 0, $max = NULL) // 48.8932
numberBetween($min = 1000, $max = 9000) // 8567
randomLetter            // 'b'
randomElements($array = array ('a','b','c'), $count = 1) // array('c')
randomElement($array = array ('a','b','c')) // 'b'
numerify($string = '###') // '609'
lexify($string = '????') // 'wgts'
bothify($string = '## ??') // '42 jz'
