## What it is
A PHP parser written in PHP that converts PHP 5.x through 8.4 code into an abstract syntax tree (AST). It provides AST traversal, modification, pretty-printing back to code, name resolution, and constant expression evaluation for static analysis and code manipulation.

## Use cases
- parse php code into an ast
- build a static analysis tool for php
- refactor php code programmatically
- generate php code from an ast
- detect deprecated php syntax in a codebase
- write a custom php linter
- transpile or transform php source code

## When to choose
- you need to parse, analyze, or transform PHP source code in a PHP project
- you want accurate location information and error-tolerant parsing of invalid code
- you need to preserve formatting when modifying code
- you are building linters, codemods, or code generators for PHP

## When to avoid
- you need to parse a language other than PHP
- you need a runtime interpreter or execution engine rather than a parser
- you need to parse PHP 4 or older code

## Facets
- artifact type: library
- maturity: stable
- function: parser, static-site-generator, developer-tools
- domain: parsers, programming-languages, developer-tools
- platform: php
