On line name generator that is dating. Faker is really a PHP collection that creates fake information for you.

It, or anonymize data taken from a production service, Faker is for you whether you need to bootstrap your database, create good-looking XML documents, fill-in your persistence to stress test.

Faker is heavily motivated 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.

Generate data that are fake


Utilize :create( that is fakerFactory to produce and initialize a faker generator, which could create information by accessing properties called following the variety of information you prefer.

Even in the event this instance shows a residential property access, each call to $ yields that are faker->name different (random) result. The More Info reason being Faker utilizes __get() secret, and forwards property that is fakerGenerator to FakerGenerator->format($home) .

Suggestion: For a generation that is quick of information, you could make use of Faker as a demand line device by way of faker-cli.

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

Techniques accepting a $timezone argument default to date_default_timezone_get() . You are able to pass a customized timezone sequence to each technique, or determine a customized timezone for several right time techniques at the same time making use of.

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

If you wish to make use of a modifier by having a value maybe perhaps not created by Faker, utilize the passthrough() technique. passthrough() simply comes back whatever value it had been provided.

FakerFactory usually takes a locale as a quarrel, 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 into the supply rule, underneath the company directory. The localization of Faker is definitely a process that is ongoing which is why we require your assistance. Never think twice to produce localized providers to your very own locale and submit 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 people of databases through the Entity classes provided by the ORM collection ( or even the populace of document shops making use of Document classes supplied by an ODM collection).

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

Remember that a number of the populators could need extra parameters. As instance the doctrine populator has a choice 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 utilising the very first Name formatter, and a line by having a TIMESTAMP kind utilizing the dateTime formatter. The entities that are resulting consequently coherent. If Faker misinterprets a line title, you can easily nevertheless specify a customized closing to be utilized for populating a column that is particular utilising the 3rd argument to addEntity() :

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

Suggestion: To ignore some columns, specify null when it comes to line names within the argument that is third of) . This is essential for columns added by a behavior:

Needless to say, Faker will not populate autoincremented primary secrets. In addition, FakerORMPropelPopulator::execute() returns the menu of inserted PKs, indexed by course:

Note: Due to your proven fact that Faker returns all of the main tips placed, the memory usage will go up drastically whenever you do batch inserts due towards the big selection 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 connect the populated Book entities to a single of this populated Author entities.

Lastly, if you’d like to perform a function that is arbitrary an entity before insertion, utilize the 4th argument associated with the addEntity() method:

Seeding the Generator

You might want to get constantly similar generated information – as an example whenever Faker that is using for evaluation purposes. The generator provides a seed() technique, which seeds the random number generator. Calling the exact same script twice with the exact same seed creates the exact same results.

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

Suggestion: Formatters won’t replicate exactly the same fake information by using 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 requires FakerProvider things to delegate the information generation for them. FakerFactory::create() really creates a FakerGenerator bundled using the standard providers. This is what takes place underneath the bonnet:

When you attempt to access home from the $faker item, the generator searches for a technique aided by the exact same title in most of the providers mounted on it. For example, calling $faker->name causes a call to FakerProviderPerson::name() . And since Faker begins utilizing the final provider, it is possible to bypass current formatters: just include a provider containing practices called following the formatters you wish to bypass.

Which means as you are able to effortlessly include your own providers to a FakerGenerator instance. A provider is normally a classfakerproviderbase that is extending . This moms and dad course lets you make use of techniques love lexify() or randomNumber() ; in addition it provides you with usage of formatters of other providers, through the protected $generator home. The brand new formatters are the general public types of the provider course.

Listed here is a good example provider for populating Book information:

To join up this provider, simply include a brand new instance of FakerProviderBook to a generator that is existing

You will make use of the two formatters that are new just about any Faker formatter:

Suggestion: A provider may also be an ordinary Old PHP Object. If so, all of the general public types of the provider become open to the generator.

Real World Usage

The following script produces a legitimate XML document:
