Faker

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.

Faker is heavily inspired by Perl's Data::Faker, and by ruby's Faker.

Faker requires PHP >= 5.3.3.

Installation

composer require fzaninotto/faker

Basic Usage

Autoloading

Faker supports both PSR-0 as PSR-4 autoloaders.

<?php
# When installed via composer
require_once 'vendor/autoload.php';

You can also load Fakers shipped PSR-0 autoloader

<?php
# Load Fakers own autoloader
require_once '/path/to/Faker/src/autoload.php';

alternatively, you can use any another PSR-4 compliant autoloader

Create fake data

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
// use the factory to create a Faker\Generator instance
$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.

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

<?php
for ($i = 0; $i < 10; $i++) {
  echo $faker->name, "\n";
}
  // Adaline Reichel
  // Dr. Santa Prosacco DVM
  // Noemy Vandervort V
  // Lexi O'Conner
  // Gracie Weber
  // Roscoe Johns
  // Emmett Lebsack
  // Keegan Thiel
  // Wellington Koelpin II
  // Ms. Karley Kiehn V

Tip: For a quick generation of fake data, you can also use Faker as a command line tool thanks to faker-cli.

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.

`Faker\Provider\Base`

randomDigit             // 7
randomDigitNot(5)       // 0, 1, 2, 3, 4, 6, 7, 8, or 9
randomDigitNotNull      // 5
randomNumber($nbDigits = NULL, $strict = false) // 79907610
randomFloat($nbMaxDecimals = NULL, $min = 0, $max = NULL) // 48.8932
numberBetween($min = 1000, $max = 9000) // 8567
randomLetter            // 'b'
// returns randomly ordered subsequence of a provided array
randomElements($array = array ('a','b','c'), $count = 1) // array('c')
randomElement($array = array ('a','b','c')) // 'b'
shuffle('hello, world') // 'rlo,h eoldlw'
shuffle(array(1, 2, 3)) // array(2, 1, 3)
numerify('Hello ###') // 'Hello 609'
lexify('Hello ???') // 'Hello wgt'
bothify('Hello ##??') // 'Hello 42jz'
asciify('Hello ***') // 'Hello R6+'
regexify('[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}'); // sm0@y8k96a.ej

`Faker\Provider\Lorem`

Modifiers

Faker provides three special providers, unique(), optional(), and valid(), to be called before any provider.

// unique() forces providers to return unique values
$values = array();
for ($i = 0; $i < 10; $i++) {
  // get a random digit, but always a new one, to avoid duplicates
  $values []= $faker->unique()->randomDigit;
}
print_r($values); // [4, 1, 8, 5, 0, 2, 6, 9, 7, 3]

// providers with a limited range will throw an exception when no new unique value can be generated
$values = array();
try {
  for ($i = 0; $i < 10; $i++) {
    $values []= $faker->unique()->randomDigitNotNull;
  }
} catch (\OverflowException $e) {
  echo "There are only 9 unique digits not null, Faker can't generate 10 of them!";
}

// you can reset the unique modifier for all providers by passing true as first argument
$faker->unique($reset = true)->randomDigitNotNull; // will not throw OverflowException since unique() was reset
// tip: unique() keeps one array of values per provider

// optional() sometimes bypasses the provider to return a default value instead (which defaults to NULL)
$values = array();
for ($i = 0; $i < 10; $i++) {
  // get a random digit, but also null sometimes
  $values []= $faker->optional()->randomDigit;
}
print_r($values); // [1, 4, null, 9, 5, null, null, 4, 6, null]

// optional() accepts a weight argument to specify the probability of receiving the default value.
// 0 will always return the default value; 1 will always return the provider. Default weight is 0.5 (50% chance).
$faker->optional($weight = 0.1)->randomDigit; // 90% chance of NULL
$faker->optional($weight = 0.9)->randomDigit; // 10% chance of NULL

// optional() accepts a default argument to specify the default value to return.
// Defaults to NULL.
$faker->optional($weight = 0.5, $default = false)->randomDigit; // 50% chance of FALSE
$faker->optional($weight = 0.9, $default = 'abc')->word; // 10% chance of 'abc'

// valid() only accepts valid values according to the passed validator functions
$values = array();
$evenValidator = function($digit) {
	return $digit % 2 === 0;
};
for ($i = 0; $i < 10; $i++) {
	$values []= $faker->valid($evenValidator)->randomDigit;
}
print_r($values); // [0, 4, 8, 4, 2, 6, 0, 8, 8, 6]

// just like unique(), valid() throws an overflow exception when it can't generate a valid value
$values = array();
try {
  $faker->valid($evenValidator)->randomElement([1, 3, 5, 7, 9]);
} catch (\OverflowException $e) {
  echo "Can't pick an even number in that set!";
}

If you would like to use a modifier with a value not generated by Faker, use the passthrough() method. passthrough() simply returns whatever value it was given.

$faker->optional()->passthrough(mt_rand(5, 15));

Localization

Faker\Factory can take a locale as an argument, to return localized data. If no localized provider is found, the factory fallbacks to the default locale (en_US).

<?php
$faker = Faker\Factory::create('fr_FR'); // create a French faker
for ($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

You can check available Faker locales in the source code, under the Provider directory. The localization of Faker is an ongoing process, for which we need your help. Don't hesitate to create localized providers to your own locale and submit a PR!

Populating Entities Using an ORM or an ODM

Faker provides adapters for Object-Relational and Object-Document Mappers (currently, Propel, Doctrine2, CakePHP, Spot2, Mandango and Eloquent are supported). These adapters ease the population of databases through the Entity classes provided by an ORM library (or the population of document stores using Document classes provided by an ODM library).

To populate entities, create a new populator class (using a generator instance as parameter), then list the class and number of all the entities that must be generated. To launch the actual data population, call the execute() method.

Note that some of the populators could require additional parameters. As example the doctrine populator has an option to specify its batchSize on how often it will flush the UnitOfWork to the database.

Here is an example showing how to populate 5 Author and 10 Book objects:

<?php
$generator = \Faker\Factory::create();
$populator = new \Faker\ORM\Propel\Populator($generator);
$populator->addEntity('Author', 5);
$populator->addEntity('Book', 10);
$insertedPKs = $populator->execute();

The populator uses name and column type guessers to populate each column with relevant data. For instance, Faker populates a column named first_name using the firstName formatter, and a column with a TIMESTAMP type using the dateTime formatter. The resulting entities are therefore coherent. If Faker misinterprets a column name, you can still specify a custom closure to be used for populating a particular column, using the third argument to addEntity():

<?php
$populator->addEntity('Book', 5, array(
  'ISBN' => function() use ($generator) { return $generator->ean13(); }
));

In this example, Faker will guess a formatter for all columns except ISBN, for which the given anonymous function will be used.

Tip: To ignore some columns, specify null for the column names in the third argument of addEntity(). This is usually necessary for columns added by a behavior:

<?php
$populator->addEntity('Book', 5, array(
  'CreatedAt' => null,
  'UpdatedAt' => null,
));

Of course, Faker does not populate autoincremented primary keys. In addition, Faker\ORM\Propel\Populator::execute() returns the list of inserted PKs, indexed by class:

<?php
print_r($insertedPKs);
// array(
//   'Author' => (34, 35, 36, 37, 38),
//   'Book'   => (456, 457, 458, 459, 470, 471, 472, 473, 474, 475)
// )

Note: Due to the fact that Faker returns all the primary keys inserted, the memory consumption will go up drastically when you do batch inserts due to the big list of data.

In the previous example, the Book and Author models share a relationship. Since Author entities are populated first, Faker is smart enough to relate the populated Book entities to one of the populated Author entities.

Lastly, if you want to execute an arbitrary function on an entity before insertion, use the fourth argument of the addEntity() method:

<?php
$populator->addEntity('Book', 5, array(), array(
  function($book) { $book->publish(); },
));

Seeding the Generator

You may want to get always the same generated data - for instance when using Faker for unit testing purposes. The generator offers a seed() method, which seeds the random number generator. Calling the same script twice with the same seed produces the same results.

<?php
$faker = Faker\Factory::create();
$faker->seed(1234);

echo $faker->name; // 'Jess Mraz I';

Tip: DateTime formatters won't reproduce the same fake data if you don't fix the $max value:
<?php
// even when seeded, this line will return different results because $max varies
$faker->dateTime(); // equivalent to $faker->dateTime($max = 'now')
// make sure you fix the $max parameter
$faker->dateTime('2014-02-25 08:37:17'); // will return always the same date when seeded
Tip: Formatters won't reproduce the same fake data if you use the rand() php function. Use $faker or mt_rand() instead:
<?php
// bad
$faker->realText(rand(10,20));
// good
$faker->realText($faker->numberBetween(10,20));

Faker Internals: Understanding Providers

A Faker\Generator alone can't do much generation. It needs Faker\Provider objects to delegate the data generation to them. Faker\Factory::create() actually creates a Faker\Generator bundled with the default providers. Here is what happens under the hood:

<?php
$faker = new Faker\Generator();
$faker->addProvider(new Faker\Provider\en_US\Person($faker));
$faker->addProvider(new Faker\Provider\en_US\Address($faker));
$faker->addProvider(new Faker\Provider\en_US\PhoneNumber($faker));
$faker->addProvider(new Faker\Provider\en_US\Company($faker));
$faker->addProvider(new Faker\Provider\Lorem($faker));
$faker->addProvider(new Faker\Provider\Internet($faker));

Whenever you try to access a property on the $faker object, the generator looks for a method with the same name in all the providers attached to it. For instance, calling $faker->name triggers a call to Faker\Provider\Person::name(). And since Faker starts with the last provider, you can easily override existing formatters: just add a provider containing methods named after the formatters you want to override.

That means that you can easily add your own providers to a Faker\Generator instance. A provider is usually a class extending \Faker\Provider\Base. This parent class allows you to use methods like lexify() or randomNumber(); it also gives you access to formatters of other providers, through the protected $generator property. The new formatters are the public methods of the provider class.

Here is an example provider for populating Book data:

<?php

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();
  }
}

To register this provider, just add a new instance of \Faker\Provider\Book to an existing generator:

<?php
$faker->addProvider(new \Faker\Provider\Book($faker));

Now you can use the two new formatters like any other Faker formatter:

<?php
$book = new Book();
$book->setTitle($faker->title);
$book->setISBN($faker->ISBN);
$book->setSummary($faker->text);
$book->setPrice($faker->randomNumber(2));

Tip: A provider can also be a Plain Old PHP Object. In that case, all the public methods of the provider become available to the generator.

Real Life Usage

The following script generates a valid XML document:

<?php
require_once '/path/to/Faker/src/autoload.php';
$faker = Faker\Factory::create();
?>
<?xml version="1.0" encoding="UTF-8"?>
<contacts>
<?php for ($i = 0; $i < 10; $i++): ?>
  <contact firstName="<?php echo $faker->firstName ?>" lastName="<?php echo $faker->lastName ?>" email="<?php echo $faker->email ?>">
    <phone number="<?php echo $faker->phoneNumber ?>"/>
<?php if ($faker->boolean(25)): ?>
    <birth date="<?php echo $faker->dateTimeThisCentury->format('Y-m-d') ?>" place="<?php echo $faker->city ?>"/>
<?php endif; ?>
    <address>
      <street><?php echo $faker->streetAddress ?></street>
