In order to make scanning easier for the eyes, it was decided that each function / formatter should have it's own section. A formatters section should contain the function name, a description and examples (in a code block).

Documented providers:

• Faker\Provider\Base
• Faker\Provider\Lorem
• Faker\Provider\DateTime
• Faker\Provider\Internet
• Faker\Provider\UserAgent
• Faker\Provider\Payment
• Faker\Provider\Color
• Faker\Provider\File
• Faker\Provider\Image
• Faker\Provider\Uuid
• Faker\Provider\Barcode
• Faker\Provider\Miscellaneous
• Faker\Provider\Biased
• Faker\Provider\HtmlLorem
