nikic/PHP-Parser

This system is a PHP parser and code analysis library that converts PHP source code into an Abstract Syntax Tree (AST). It provides tools for parsing, building, and pretty-printing PHP code across multiple versions, supporting modern language features like enums, attributes, and type declarations. The library includes a builder API for AST construction, visitors for tree traversal, and utilities for format preservation and static analysis.

The project replaced its legacy PHP parser infrastructure with a new grammar-based system, removing obsolete classes and build tools. This refactor was accompanied by extensive test coverage for the new parser, covering expressions, statements, and the pretty printer across multiple PHP versions.

The project underwent a comprehensive refactoring of its abstract syntax tree, replacing array-based structures with strongly typed, PHP 7+ compatible node classes. This period introduced a fluent builder API for AST construction, expanded support for modern PHP features like enums and attributes, and added new node visitors for traversal and analysis.

This period focused on extending the library to support PHP 7 and PHP 8 syntax, including new language features like match expressions, enums, and attributes. Significant effort was also dedicated to implementing format-preserving pretty-printing and adding comprehensive test coverage for the new parsers and formatting utilities.
