Whether you ought to bootstrap your database, create good-looking XML documents, fill-in your persistence to stress test drive it, or anonymize information obtained from a manufacturing solution, Faker is for you.
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.
You’ll be able to 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 create information by accessing properties known as following the form of information you desire.
Just because this instance shows home access, each call to $ yields that are faker->name different (random) result. The reason being Faker makes use of __get() secret, and forwards FakerGenerator->$property telephone calls to FakerGenerator->format($home) .
Suggestion: For the generation that is quick of information, you are able to utilize Faker being a demand line device because 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 these, packed in “providers”. Listed here is a variety of the bundled formatters into the standard locale.
Practices accepting a $timezone argument default to date_default_timezone_get() . You’ll pass a customized timezone sequence to each technique, or determine a customized timezone for several time practices simultaneously utilizing.
Faker provides three unique providers, unique() , optional() , and valid() , become called before any provider.
If you’d like to utilize a modifier having a value not produced by Faker, utilize the passthrough() technique. passthrough() merely comes back whatever value it had been offered.
FakerFactory takes a locale as a disagreement, to go back localized information. If no localized provider is discovered, the factory fallbacks into the standard locale (en_US).
You can examine available Faker locales when you look at the supply rule, beneath the company directory. The localization of Faker can be an ongoing procedure, which is why we want your help. 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 mappers that are object-Documentpresently, 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 utilizing Document classes given by an ODM library).
To populate entities, develop a brand new populator course (using a generator example as parameter), then list the course and number of all entities that must definitely be produced. To introduce the data that are actual, call the execute() technique.
Observe that a few of the populators could need parameters that are additional. As instance the doctrine populator has an alternative to specify its batchSize how usually it will flush the UnitOfWork towards the database.
The following is an illustration showing just how to populate 5 Author and 10 Book objects:
The populator makes use of column and name kind guessers to populate each line with appropriate information. For example, Faker populates a column called first_name with the name that is first, and a line by having a TIMESTAMP kind with the dateTime formatter. The resulting entities are 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.
Suggestion: To disregard some columns, specify null for the line names within the 3rd argument of addEntity() . Normally, this is required for columns added by way of a behavior:
Needless to say, Faker will not populate autoincremented keys that are primary. 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 primary keys placed, the memory usage is certainly going up drastically once you do batch inserts busty ukrainian brides due towards the big selection of data.
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 1 regarding the populated Author entities.
Finally, if you wish to perform a function that is arbitrary an entity before insertion, utilize the 4th argument associated with the addEntity() technique:
Seeding the Generator
You might get constantly similar generated information – as an example whenever Faker that is using for assessment 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 if you are using the rand() php function. Make use of $ mt_rand( or faker) alternatively:
Faker Internals: Understanding Providers
A FakerGenerator alone can’t do much generation. It requires FakerProvider things to delegate the info generation in their mind. FakerFactory::create() really creates a FakerGenerator bundled using the standard providers. Here’s what takes place beneath the bonnet:
If you you will need to access a residential property regarding the $faker item, the generator actively seeks an approach with all the name that is same all of the providers attached with it. A call to FakerProviderPerson::name() for instance, calling $faker->name triggers . And since Faker begins using the provider that is last it is simple to bypass current formatters: simply add a provider containing techniques known as following the formatters you need to bypass.
Which means you could 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 utilize techniques lexify( that is like or randomNumber() ; in addition provides you with usage of formatters of other providers, through the protected $generator home. The brand new formatters are the general public ways of the provider class.
Listed here is an illustration provider for populating Book information:
To join up this provider, simply include an innovative new instance of FakerProviderBook to a current generator:
You will make use of the two brand new formatters like just about any Faker formatter:
Suggestion: A provider can be an ordinary Old PHP Object. All the public methods of the provider become available to the generator in that case.
Real World Use
The script that is following a legitimate XML document:
Operating this script creates a document appearing like:
