This is a PHP 5.2 to PHP 8.0 parser written in PHP. Its purpose is to simplify static code analysis and manipulation.

[**Documentation for version 4.x**](https://github.com/nikic/PHP-Parser/tree/master/doc) (stable; for running on PHP >= 7.0; for parsing PHP 5.2 to PHP 8.0).

[Documentation for version 3.x](https://github.com/nikic/PHP-Parser/tree/3.x/doc) (unsupported; for running on PHP >= 5.5; for parsing PHP 5.2 to PHP 7.2).

Features
--------

[](#features)

The main features provided by this library are:

- Parsing PHP 5, PHP 7, and PHP 8 code into an abstract syntax tree (AST).
    - Invalid code can be parsed into a partial AST.
    - The AST contains accurate location information.
- Dumping the AST in human-readable form.
- Converting an AST back to PHP code.
    - Experimental: Formatting can be preserved for partially changed ASTs.
- Infrastructure to traverse and modify ASTs.
- Resolution of namespaced names.
- Evaluation of constant expressions.
- Builders to simplify AST construction for code generation.
- Converting an AST into JSON and back.
