$faker->optional($weight = 0.5, $default = false)->randomDigit() // 50% chance of FALSE optional() accepts a default argument to specify the default value to return. $faker->optional($weight = 100)->randomDigit // 0% chance of NULL $faker->optional($weight = 10)->randomDigit // 90% chance of NULL $faker->optional($weight = 0.9)->randomDigit() // 10% chance of NULL $faker->optional($weight = 0.1)->randomDigit() // 90% chance of NULL Please note that the weight can be provided as float (0 / 1.0) or int (0 / 100) 0 will always return the default value 1.0 will always return the provider. optional() accepts a weight argument to specify the probability of receiving the default value. optional() sometimes bypasses the provider to return a default value instead (which defaults to NULL)įor ($i = 0 $i optional()->randomDigit()
tip: unique() keeps one array of values per provider $faker->unique($reset = true)->randomDigitNotNull() // will not throw OverflowException since unique() was reset
you can reset the unique modifier for all providers by passing true as first argument providers with a limited range will throw an exception when no new unique value can be generatedįor ($i = 0 $i unique()->randomDigitNotNull() Įcho "There are only 9 unique digits not null, Faker can't generate 10 of them!" unique() forces providers to return unique values "\n" įaker provides three special providers, unique(), optional(), and valid(), to be called before any provider. This is because Faker uses _call() magic, and forwards Faker\Generator->$method() calls to Faker\Generator->format($method, $attributes). 'Numquam ut mollitia at consequuntur inventore dolorem.'Įach call to $faker->name() yields a different (random) result. use the factory to create a Faker\Generator instance Use Faker\Factory::create() to create and initialize a faker generator, which can generate data by calling methods named after the type of data you want. Require_once '/path/to/Faker/src/autoload.php' Īlternatively, you can use any other PSR-4 compliant autoloader Create fake data # You can also load Fakers shipped PSR-0 autoloader // load Faker autoloader composer require fakerphp/faker Basic Usage # Autoloading #įaker supports both PSR-0 as PSR-4 autoloaders. It's heavily inspired by Perl's Data::Faker, and by Ruby's Faker. Whether you need to bootstrap your database, create good-looking XML documents, fill-in your persistence to stress test it, or anonymize data taken from a production service, Faker is for you. Faker is a PHP library that generates fake data for you.
