## Description

Faker is a PHP library for creating realistic synthetic data used for testing, prototyping, and populating database entities. It serves as a test data generator and localized mocking tool capable of producing synthetic names, addresses, and identifiers specific to various countries and languages.

The library provides mechanisms to ensure data consistency and quality, including deterministic seeding to produce identical data sequences across executions and stateful uniqueness tracking to prevent duplicate values. It also supports probability-weighted optionality to simulate missing data and custom value filtering to ensure generated output meets specific validation criteria.

The tool covers a broad range of data domains, including personal information, geographic addresses, internet metadata, and system-level identifiers. It further includes specialized generators for financial payment details, date and time primitives, and placeholder content such as Lorem Ipsum text, color values, and image placeholders. These capabilities allow for the population of database entities via ORM mapping and the creation of UI prototype mockups.
