Ionizer provides strict typing and input validation for dynamic inputs (i.e. HTTP request parameters). **Requires PHP 8.1 or higher.**

For PHP 7 and 8.0 support, please refer to the [v1.x](https://github.com/paragonie/ionizer/tree/v1.x) branch.

What is Ionizer?
----------------

[](#what-is-ionizer)

Ionizer is a structured input filtering system ideal for HTTP form data.

### Why is Ionizer important?

[](#why-is-ionizer-important)

Aside from the benefits of being able to strictly type your applications that accept user input, Ionizer makes it easy to mitigate [some NoSQL injection techniques](https://www.php.net/manual/en/mongodb.security.request_injection.php). Learn more about [preventing NoSQL injection with Ionizer](docs/nosql-injection-prevention.md).
