Overview
--------

[](#overview)

This library allows you to extract, filter and validate individual fields from an associative array. It can be used, as an example, to validate request variables sent from a web browser. You give each parameter a "name", define the "context" and call "process"; the result will be the value extracted from the context or an error message in case of not conforming to one or more validation filters. Many predefined filters and validators are available from a "finger-friendly" API. You can also specify a fallback value to be returned in case of validation error.
