On the web name generator that is dating. Faker is just a PHP collection that creates fake information for you.

Whether you ought to bootstrap your database, create good-looking XML documents, fill-in your perseverance to stress test that, or anonymize information extracted from a manufacturing solution, Faker is actually for you.

Faker is heavily prompted by Perl’s information::Faker, and also by ruby’s Faker.

Faker calls for PHP >= 5.3.3.

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

instead, you can make use of any another PSR-4 compliant autoloader

Generate fake data


Utilize :create( that is fakerFactory to produce and initialize a faker generator, which could create information by accessing properties known as following the style of information you desire.

Even though this instance shows a house access, each call to $ yields that are faker->name different (random) result. It is because Faker makes use of __get() miracle, and forwards FakerGenerator->$property calls to FakerGenerator->format($home) .

Suggestion: For a generation that is quick of information, you may also utilize Faker as a demand line device as a result of faker-cli.

Each one of the generator properties (like title , target , and lorem ) are known as “formatters”. A faker generator has its own of those, packed in “providers”. The following is a summary of the bundled formatters into the standard locale.

Techniques accepting a $timezone argument default to date_default_timezone_get() . It is possible to pass a customized timezone sequence to each technique, or determine a customized timezone for several right time practices at the same time utilizing.

Faker provides three providers that are special unique() , optional() , and valid() , become called before any provider.

If you’d like to make use of a modifier by having a value perhaps maybe not produced by Faker, utilize the passthrough() technique. passthrough() merely comes back whatever value it had been offered.

FakerFactory may take a locale as a disagreement, to come back localized information. If no provider that is localized discovered, the factory fallbacks to your standard locale (en_US).

You can examine available Faker locales in the supply rule, underneath the company directory. The localization of Faker can be a process that is ongoing which is why we truly need your assistance. Do not think twice to produce localized providers to your locale that is own and a PR!

Populating Entities Using an ORM or an ODM

Faker provides adapters for Object-Relational and Object-Document Mappers (presently, Propel, Doctrine2, CakePHP, Spot2, Mandango and Eloquent are supported). These adapters relieve the populace of databases through the Entity classes provided by the ORM collection ( or perhaps the populace of document stores making use of Document classes supplied by an ODM collection).

To populate entities, create a populator that is new (using a generator example as parameter), then list the course and number of all entities that really must be produced. To introduce the real information population, call the execute() technique.

Remember that a number of the populators could need additional parameters. As instance the doctrine populator has an alternative to specify its batchSize on what frequently it shall flush the UnitOfWork to your database.

Listed here is an illustration showing just how to populate 5 Author and 10 Book things:

The populator utilizes column and name kind guessers to populate each line with appropriate information. By way of example, Faker populates a column known as first_name utilizing the very first Name formatter, and a line with a TIMESTAMP kind making use of the dateTime formatter. The entities that are resulting consequently coherent. If Faker misinterprets a line title, you are able to nevertheless specify a customized closing to be utilized for populating a specific line, utilising the 3rd argument to addEntity() :

In this instance, Faker will imagine a formatter for several columns except ISBN , which is why the offered function that is anonymous be properly used.

Tip: To disregard some columns, specify null when it comes to line names into the 3rd argument of addEntity() . Normally required for columns added by way of a behavior:

Needless to say, Faker will not populate autoincremented main tips. In addition, FakerORMPropelPopulator::execute() comes back the directory of inserted PKs, indexed by course:

Note: Due to your proven fact that Faker returns all of the main secrets placed, the memory usage is certainly going up drastically once you do batch inserts due towards the big range of information.

The Book and Author models share a relationship in the previous example. Since Author entities are populated first, Faker is sensible adequate to relate the populated Book entities to at least one of this populated Author entities.

Finally, if you’d like to perform a function that is arbitrary an entity before insertion, utilize the 4th argument for the addEntity() technique:

Seeding the Generator

You might want to get constantly exactly the same generated information – as an example whenever making use of Faker for unit screening purposes. The generator supplies a seed() technique, which seeds the number generator that is random. Calling the script that is same with the exact same seed creates exactly the same outcomes.

Suggestion: DateTime formatters will not replicate exactly the same fake information if you do not fix the $ value that is max

Suggestion: Formatters won’t replicate exactly the same fake information if you utilize the rand() php function. Make use of $faker or mt_rand() alternatively:

Faker Internals: Understanding Providers

A FakerGenerator alone can’t do much generation. It needs FakerProvider things to delegate the info generation in their mind. FakerFactory::create() really creates a FakerGenerator bundled using the standard providers. This is what occurs underneath the bonnet:

Once you attempt to access a house regarding the $faker item, the generator actively seeks a technique utilizing the exact same title in most of the providers mounted on it. By way of example, calling $faker->name causes a call to FakerProviderPerson::name() . And because Faker begins because of the final provider, it is possible to bypass current formatters: simply put in a provider containing techniques called following the formatters you wish to override.

This means that one may effortlessly add your providers that are own a FakerGenerator instance. A provider is generally a course expanding fakerproviderbase . This moms and dad course lets you utilize techniques love lexify() or randomNumber() ; moreover it provides use of formatters of other providers, through the protected $generator home. The formatters that are new the public ways of the provider course.

The following is an illustration provider for populating Book information:

To join up this provider, just include a fresh instance of FakerProviderBook to a generator that is existing

You can now utilize the two brand new formatters like every other Faker formatter:

Suggestion: A provider can be an ordinary Old PHP Object. If so, most of the general public ways of the provider become accessible to the generator.

Real World Usage

The script that is following a legitimate XML document:

Operating this script creates a document appearing like:
