ReverseRegex is a PHP library that generates matching strings from regular expressions, useful for producing realistic test data for forms, databases, and regex test suites. It lexes and parses a supported subset of regex syntax, then uses a pluggable random generator to emit strings that satisfy the pattern.

Ideal for property-based testing and fixtures, it supports literals, groups, character classes, ranges (including Unicode via \X{####}), and quantifiers—while documenting limitations (e.g., no \p Unicode properties).

Generate strings from regex patterns (e.g. [a-z]{10})

Deterministic output via seedable random generators
Support for character classes, groups, ranges, and quantifiers
