This is a PHP 5.2 to PHP 8.1 parser written in PHP. Its purpose is to simplify static code analysis and manipulation.

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.
