Installing Fake Package

To get started we need to install the faker package using the composer package manager.

To install the fake package run the following command

composer require fzaninotto/faker

Generate fake data

Create an instance of the faker package

$faker = Faker\Factory::create();

Using the created instance of the faker package we can generate different fake data 

For example:

$faker->firstName

It will generate fake first names like Peter

$faker->lastName

It will generate fake last names like  Smith

$faker->email

It will generate fake emails like  email@email.com

$faker->streetAddress

It will generate fake addresses like  123 street addresses.

$faker->city

It will generate fake cities like  Lahore

$faker->state

It will generate fake states like  Punjab

$faker->postcode

It will generate a fake postcode like  54800

$faker->randomNumber(2)

It will generate fake 2 random numbers like  12

Others are as follows

$faker->title

$faker->text

What is formatted?

Generator properties (title, city ) are known as formatters.

Here we have some of them listed below.

1. Faker\Provider\DateTime
2. Faker\Provider\Color
3. Faker\Provider\Lorem
4. Faker\Provider\Internet
5. Faker\Provider\Payment
6. Faker\Provider\en_US\Company
7. Faker\Provider\en_US\PhoneNumber
8. Faker\Provider\en_US\Person
9. Faker\Provider\en_US\Address

Multilingual / Localization

If we need fake data in different languages then we can achieve it by giving 

a language params during instance creation. 

For example:

$faker_fr = Faker\Factory::create('fr_FR');

It will create a French fake for us and all.
