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
