A parser for PHP written in Go

Go Report Card Exago Exago GoDoc

Try it online: demo

Features:

  • Fully support PHP5 and PHP7 syntax
  • Abstract syntax tree representation
  • Traversing AST
  • Namespace resolver

Install

go get github.com/z7zmey/php-parser

Example

package main

import (
	"bytes"

	"github.com/z7zmey/php-parser/php7"
	"github.com/z7zmey/php-parser/visitor"
)

func main() {
	src := bytes.NewBufferString(`<? echo "Hello world";`)
	nodes, comments, positions := php7.Parse(src, "example.php")

	visitor := visitor.Dumper{
		Indent:    "",
		Comments:  comments,
		Positions: positions,
	}
	nodes.Walk(visitor)
}

CLI dumper

$GOPATH/bin/php-parser /path/to/file/or/dir

Namespace resolver

Namespace resolver is a visitor that traverses nodes and resolves nodes fully qualified name. It does not change AST but collects resolved names into map[node.Node]string

  • For Class, Interface, Trait, Function, ConstList nodes collects name with current namespace.
  • For Name, Relative, FullyQualified nodes resolves use aliases and collects a fully qualified name.

Roadmap

  • Lexer
  • PHP 7 syntax analyzer
  • AST nodes
  • AST visitor
  • AST dumper
  • node position
  • handling comments
  • PHP 5 syntax analyzer
  • Tests
  • Namespace resolver
  • PhpDocComment parser
  • Error handling
  • Stabilize api
  • Documentation
  • Pretty printer
  • Code flow graph
