## What it is
A PHP library for validating JSON data structures against JSON Schema, supporting Draft-3, Draft-4, Draft-6, Draft-7, and Draft 2019-09. It provides a simple Validator API with error reporting and type coercion, and is compliance-tested via the Bowtie suite.

## Use cases
- validate  payloads against a schema in php
- validate api request bodies with  schema
- check  config files conform to a schema
- validate  documents against draft-7 schemas
- coerce types when validating http input in php

## When to choose
- you need standards-compliant JSON Schema validation in a PHP project
- you need support for multiple JSON Schema drafts including 2019-09
- you want a Composer-installable validator that integrates with Laravel or Symfony

## When to avoid
- you need the latest JSON Schema drafts (2020-12 or newer)
- you are not working in PHP
- you need full feature coverage of newer drafts, which may be incomplete
