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 obtained from a manufacturing solution, Faker is actually for you.
Faker is heavily influenced by Perl’s information::Faker, and by ruby’s Faker.
Faker calls for PHP >= 5.3.3.

Faker supports both PSR-0 as PSR-4 autoloaders.
You may load Fakers shipped PSR-0 autoloader
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, that may produce information by accessing properties known as following the sort of information you prefer.
No matter if this instance shows a residential property access, each call to $ yields ukrainian dating free that are faker->name different (random) result. The reason being Faker utilizes __get() miracle, and forwards FakerGenerator->$property telephone calls to FakerGenerator->format($home) .
Suggestion: For the fast generation of fake information, you are able to make use of 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 range of the bundled formatters within the standard locale.
Practices accepting a $timezone argument default to date_default_timezone_get() . You can easily pass a customized timezone sequence to each technique, or determine a customized timezone for several time practices at a time making use of.
Faker provides three providers that are special unique() , optional() , and valid() , become called before any provider.
If you want to make use of a modifier having a value perhaps perhaps maybe not created by Faker, make use of the passthrough() technique. passthrough() merely returns whatever value it had been offered.
FakerFactory may take a locale as a quarrel, to come back localized information. If no localized provider is discovered, the factory fallbacks towards the standard locale (en_US).
You can examine available Faker locales when you look at the supply rule, underneath the company directory. The localization of Faker is definitely a process that is ongoing which is why we are in need of your help. Do not think twice to produce localized providers to your very own locale and submit a PR!
Faker provides adapters for Object-Relational and Object-Document Mappers (presently, Propel, Doctrine2, CakePHP, Spot2, Mandango and Eloquent are supported). These adapters ease the populace of databases through the Entity classes provided by the ORM collection ( or the populace of document shops utilizing Document classes given 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 created. To introduce the real information population, call the execute() technique.
Observe that a number of the populators could require extra parameters. As instance the doctrine populator has a choice to specify its batchSize how frequently it shall flush the UnitOfWork to your database.
The populator utilizes column and name kind guessers to populate each line with appropriate information. For example, Faker populates a column known as first_name making use of the name that is first, and a line with a TIMESTAMP type utilizing the dateTime formatter. The resulting entities are consequently coherent. If Faker misinterprets a line title, it is possible to nevertheless specify a customized closing to be utilized for populating a specific column, utilizing 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 utilized.
Suggestion: To ignore some columns, specify null for the line names when you look at the argument that is third of) . Normally, this is essential 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 class:
Note: Due to your proven fact that Faker returns most of the main tips placed, the memory usage will go up drastically once you do batch inserts due towards the list that is big of.
In the earlier instance, the Book and Author models share a relationship. Since Author entities are populated first, Faker is sensible adequate to connect the populated Book entities to 1 of this populated Author entities.
Finally, should you want to perform a function that is arbitrary an entity before insertion, utilize the 4th argument regarding the addEntity() technique:
You might get constantly equivalent generated data – by way of example whenever making use of Faker for unit screening purposes. The generator delivers 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 equivalent fake information by using the rand() php function. Make use of $faker or mt_rand() alternatively:
A FakerGenerator alone can’t do generation that is much. It requires FakerProvider things to delegate the info generation for them. FakerFactory::create() really creates a FakerGenerator bundled using the standard providers. Here’s what occurs underneath the bonnet:
If you attempt to access a house in the $faker item, the generator searches for a technique because of the exact same title in most of the providers attached with it. A call to FakerProviderPerson::name() for instance, calling $faker->name triggers . And since Faker begins using the final provider, it is simple to bypass existing formatters: just 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 classfakerproviderbase that is extending . This moms and dad course enables you to utilize techniques lexify( that is like or randomNumber() ; in addition offers you usage of formatters of other providers, through the protected $generator home. The formatters that are new the general public types of the provider course.
The following is an illustration provider for populating Book information:
To join up this provider, simply include a unique instance of FakerProviderBook to a generator that is existing
You will utilize the two brand new formatters like any kind of Faker formatter:
Tip: A provider may also be an ordinary Old PHP Object. All the public methods of the provider become available to the generator in that case.
The script that is following a legitimate XML document:
Operating this script creates a document searching like:
