Whether you’ll want to bootstrap your database, create good-looking XML documents, fill-in your perseverance to stress test drive it, or anonymize information extracted from a manufacturing solution, Faker is for you.
Faker is heavily motivated by Perl’s Data::Faker, and also by ruby’s Faker.
Faker calls for PHP >= 5.3.3.

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

Generate fake data
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 would like.
Regardless of if this instance shows a house access, each call to $faker->name yields a different (random) result. The reason being Faker makes use of __get() miracle, and forwards property that is fakerGenerator to FakerGenerator->format($home) .
Suggestion: For a generation that is quick of information, you’ll be able to 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 within the standard locale.
Practices accepting a $timezone argument default to date_default_timezone_get() . It is possible to pass a customized timezone sequence to every technique, or determine a customized timezone for several time techniques at a time making use of.
Faker provides three unique providers, unique() , optional() , and valid() , become called before any provider.
If you wish to utilize a modifier by having a value perhaps perhaps not created by Faker, make use of the passthrough() technique. passthrough() merely comes back whatever value it had been offered.
FakerFactory takes 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 should check available Faker locales into the supply rule, beneath the company directory. The ukrainian mail order bride localization of Faker is a process that is ongoing which is why we are in need of your assistance. Do not wait 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 mappers that are object-Documentpresently, Propel, Doctrine2, CakePHP, Spot2, Mandango and Eloquent are supported). These adapters relieve the populace of databases through the Entity classes provided by an ORM collection ( or perhaps the populace of document shops utilizing Document classes given by an ODM collection).
To populate entities, produce a populator that is new (using a generator example as parameter), then list the course and number of all of the entities that needs to be produced. To introduce the data that are actual, call the execute() technique.
Observe 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 will flush the UnitOfWork to your database.
Let me reveal an illustration showing simple tips to populate 5 Author and 10 Book things:
The populator makes use of title and line kind guessers to populate each line with appropriate information. As an example, Faker populates a column known as first_name utilizing the very first Name formatter, and a line with a TIMESTAMP kind utilizing the dateTime formatter. The resulting entities are consequently coherent. If Faker misinterprets a line title, you are able to nevertheless specify a custom closure 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 many columns except ISBN , which is why the provided anonymous function will be properly used.
Suggestion: To disregard some columns, specify null for the line names within the 3rd argument of addEntity() . It’s usually required for columns added by a behavior:
Needless to say, Faker will not populate autoincremented keys that are primary. In addition, FakerORMPropelPopulator::execute() comes back the menu of inserted PKs, indexed by course:
Note: Due to your proven fact that Faker returns most of the main secrets placed, the memory usage will go up drastically once you do batch inserts due to your list that is big of.
In the last example, the Book and Author models share a relationship. Since Author entities are populated first, Faker is sensible sufficient to connect the populated Book entities to a single associated with the populated Author entities.
Finally, if you wish to perform a function that is arbitrary an entity before insertion, make use of the 4th argument associated with the addEntity() technique:
Seeding the Generator
You might want to get constantly exactly the same generated information – for example whenever Faker that is using for assessment purposes. The generator provides a seed() technique, which seeds the random quantity generator. Calling the script that is same with similar seed creates the exact 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 equivalent fake information if you are using the rand() php function. Make use of $faker or mt_rand() alternatively:
Faker Internals: Understanding Providers
A FakerGenerator alone can’t do generation that is much. It requires FakerProvider things to delegate the information generation for them. FakerFactory::create() really creates a FakerGenerator bundled with all the standard providers. Some tips about what occurs underneath the bonnet:
When you you will need to access a residential property regarding the $faker item, the generator searches for a technique because of the name that is same all of the providers attached with it. For example, calling $faker->name causes a call to FakerProviderPerson::name() . And because Faker begins utilizing the final provider, it is simple to bypass current formatters: simply include a provider containing practices known as following the formatters you intend to bypass.
Which means that one may effortlessly include your very own providers to a FakerGenerator instance. A provider is generally a course expanding fakerproviderbase . This moms and dad course lets you make use of techniques love lexify() or randomNumber() ; moreover it offers you use of formatters of other providers, through the protected $generator home. The formatters that are new the general public ways of the provider course.
Listed here is an illustration provider for populating Book information:
To join up this provider, simply include a unique instance of FakerProviderBook to a current generator:
You can now make use of the two brand new formatters like some other Faker formatter:
Suggestion: A provider may also be a Plain Old PHP Object. All the public methods of the provider become available to the generator in that case.
